    Full Text Available This work attempts to design and implement in hardware a transducer with a nonlinear response using potentiometer. Potentiometer is regarded as a linear transducer, while a the response of a nonlinear transducer can be treated as a concatenation of linear segments made out of the response curve of an actual nonlinear transducer at the points of inflections being exhibited by the nonlinear curve. Each straight line segment is characterized by its slope and a constant, called the y-intercept, which is ultimately realized by a corresponding electronic circuit. The complete circuit diagram is made of three stages: (i the input stage for range selection, (ii a digital logic to make appropriate selection, (iii a conditioning circuit for realizing a given straight-line segment identified by its relevant slope and reference voltage. The simulation of the circuit is carried using MULTISIM, and the designed circuit is afterward tested to verify that variations of the input voltage give us an output voltage very close to the response pattern envisaged in the analytical stage of the design. The utility of this work lies in its applications in emulating purpose built transducers that could be used to nicely emulate a transducer in a real world system that is to be controlled by a programmable digital system.

    Full Text Available El proceso de descentralización territorial que pretendía la Asamblea Nacional Constituyente de 1991 se ha visto truncado por las políticas adoptadas por gobiernos centralistas a través de reformas constitucionales y de los desarrollos normativos de estas. La adopción de las políticas centralistas ha tenido como principal argumento la corrupción de los entes territoriales y la cientificidad del Gobierno nacional en el manejo de los recursos. No obstante, la realidad de los entes territoriales ha demostrado que las políticas centralistas no contribuyen al mejoramiento de sus condiciones políticas y económicas. Esto ha generado una seria reducción de la autonomía administrativa y política que deberían tener los entes territoriales según los parametros originales de la Constitución Política, lo que ha fortalecido el rezago económico y administrativo que tenían dichos entes con anterioridad a la Constitución Política de 1991.

    It has been designed and characterized the water level detector using MW22B Multi-Turn Potentiometer. The electrical angle of potentiometer used has been characterized, that is 3600°±7° and its linearity independent is ±0.25%. The realized system consists of three parts; mechanical system of sensor, signal conditioning circuit and output system. The mechanical system of sensor is destined to convert linearly the value of potentiometer resistance to the water level variation. The signal conditioning consists of analog and digital system especially microcontroller circuit. The value of water level measured is shown on the 2×16 characters LCD. The range of measured water level is 0 - 2.7 m that correspond to the potentiometer resistance range of 100Ω - 100 kΩ. The obtained vertical resolution of instrument is about 0.03 m and the error of system is ˜1.11%.

    Full Text Available Component testing is one of the most important tasks before it is put to use in any application. In this direction linearity of potentiometer plays an important role, especially the multi turn rotary potentiometers. This is because; such potentiometers are used in vital applications such as in aircrafts for the maintenance of certain pressure systems and as rotary position sensors. Testing for linearity is an important task in such a scenario. Testing of components calls for an analog to digital converter for converting analog information into digital domain. The main aim of the present work is to design and develop an embedded system to test the linearity of such a potentiometer. Such a system is portable. The hardware makes use of a stepper motor, a Darlington driver IC ULN 2003 and a small jig to attach the potentiometer to a stepping motor. Philips ARM LPC 2103-mixed signal controller controls the entire assembly. Software is developed to acquire data from potentiometer, to store the data on the on-chip memory, to display it on LCD, and to send the same to PC on serial lines using MAX-232. The linearity plot is displayed on the system monitor.

    marxista. No obstante, en los últimos desarrollos de ambas escuelas se está produciendo una convergencia creciente en torno al reconocimiento de la autonomía, cuando menos relativa, de las instituciones políticas y de su calidad de actores con entidad propia, alejándose de los modelos predominantemente societarios que las caracterizaban. Ese reconocimiento de un margen de autonomía de lo político encuentra confirmación en los estudios empíricos de Gobierno de Partidos que se han realizado en los últimos años, en los que se muestra que la actividad gubernamental no puede ser explicada desde ninguna tesis de dependencia societaria debido a la particular posición en la que se ubica el Gobierno dentro del sistema político. No obstante, esa convergencia aún está escasamente difundida en nuestro ámbito académico. Por otra parte, a pesar de lo coincidente de sus conclusiones y propuestas, no existe ninguna referencia cruzada entre el trabajo teórico de neopluralistas y neomarxistas y la labor empírica del estudio del Gobierno de Partidos. Este artículo se orienta a mostrar las líneas principales de esa convergencia de paradigmas politológicos. Para ello se analizan brevemente los desarrollos del pluralismo tradicional hasta su reformulación en el neopluralismo contemporáneo y la evolución del neomarxismo desde su variante estructuralista hasta el neomarxismo postestructuralista de Bob Jessop, a la vez que se pretende mostrar su adecuación a los hallazgos empíricos de los estudiosos del Gobierno de Partidos.

    Full Text Available Muchas mujeres sin titulación académica ni universitaria, las «otras mujeres», están participando en escuelas de personas adultas y en diferentes asociaciones educativas y culturales. Si las personas educadoras defendemos una educación democrática, en la línea de la pedagogía de la autonomía de Paulo Freire, tenemos el papel de ofrecer el máximo número de oportunidades a todas las mujeres, sobre todo a las que se encuentran en más desigualdad por no tener una titulación académica y no haber podido participar de su derecho a la educación con anterioridad. Freire nos invita a ser profesionales de la educación coherentes con nuestro discurso, personas comprometidas y esperanzadas, profesionales con ilusión. Las «otras mujeres» están demostrando, día a día, en las clases de alfabetización, en las tertulias literarias, en los grupos de mujeres, en los congresos de alfabetización, o participando en proyectos europeos, que la solidaridad entre las mujeres es la base para poder avanzar todas juntas, académicas y no académicas, hacia la superación de las desigualdades de todas las mujeres. Existen muchas asociaciones y grupos de mujeres que se basan en el diálogo y en la igualdad de las diferencias, defendiendo el Feminismo Dialógico. Así, mujeres de muy diferentes culturas y estilos de vida deciden qué educación quieren, cómo la quieren, para qué, qué sueños tienen… Somos estando, dice Freire, desde la coherencia, la ilusión, la solidaridad

    Full Text Available The implementation of the model of territorial organization established by the Spanish Constitution of 1978 involves the creation of non state-wide institutions with legislative powers, and the celebration of regional elections in order to decide the composition of the autonomous parliaments. The turnout registered in this type of contests is persistently and generally lower than in general elections. Those citizens that participate in the general but not in the regional elections are known as differential non-voters. Despite this pattern of non-voting is repeated election after election in all the communities, its magnitude and consequences differ in each case. In this paper, the causes of this variation are explored by using aggregated data of turnout in both types of elections across regions and over time. Results from the specified econometric models seem to point out the need to resort to several socio-demographic, political and institutional factors to explain differential abstention in the decentralized Spain.

    La implementación del modelo de organización territorial establecido por la Constitución española de 1978 supone la creación de entidades no estatales con capacidad legislativa y la celebración de elecciones regionales para decidir la composición de los parlamentos autonómicos. La participación registrada en este tipo de comicios es persistente y generalizadamente más baja que la que se da en las elecciones a Cortes Generales. Aquellos ciudadanos que votan en las elecciones generales pero no en las autonómicas son conocidos como abstencionistas diferenciales. A pesar de que este patrón abstencionista se repite elección tras elección en todas las comunidades, su magnitud y consecuencias difieren en cada caso.

    Full Text Available Some fundamental trends of the recent reorganization of economic activities in Spain are defined by the growing concentration in certain urban areas of certain economic activities, especially those related to the creation, management and use of innovation and knowledge, and selective decentralization of others. The main hypothesis of this work assumes that capital of autonomy is a factor that exerts some influence on the structure of economic activities in a city. In this paper we study the scope of this thesis referred to municipalities and provincial capitals of autonomy between 1981 and 2011. The study conducted helps verify the trend towards concentration of capital in certain activities of the knowledge economy. The good connectivity of cities or the proximity to large urban areas are attractive forces; the capital of autonomy has a limited influence on intermediate sized nuclei located in dynamic regional contexts.Parte de la reorganización reciente de las actividades económicas en España se define por la concentración en determinadas áreas urbanas de ciertas actividades económicas, especialmente las relacionadas con la creación, gestión y uso de la innovación y el conocimiento, y por la descentralización selectiva de otras.

En este marco se estudia el alcance de estas tesis referidas a los municipios capitales de provincia y de autonomía entre 1981 y 2011. El estudio permite constatar la tendencia a la concentración en determinadas capitales de las actividades de la «economía del conocimiento» . La buena conectividad de las ciudades o la cercanía a grandes áreas urbanas son fuerzas de atracción de este tipo de actividades; la capitalidad de autonomía tiene una influencia limitada en núcleos de tamaño intermedio ubicados en contextos regionales

    2013-12-01

    Full Text Available Dentro de la actividad contractual de la administración pública en Colombia, se ha permitido, por disposición de la normativa constitucional y del legislador, la aplicación del principio de la autonomía de la voluntad, para que los sujetos contratantes dentro del negocio jurídico público construyan y establezcan las cláusulas que determinen las condiciones del contrato que celebran. El alcance de la autonomía de la voluntad debe ser analizado y sometido a una reflexión, frente a la institución de las cláusulas excepcionales al Derecho común, utilizadas por las entidades del Estado, dentro de la relación jurídica contractual que genera con el contratista. La existencia de las cláusulas excepcionales ha sido justificada por la consecución de los fines del Estado y, en especial, del interés público, pero no se ha reflexionado sobre la esencia de la figura. La aplicación de la institución en las relaciones contractuales del Estado se ha desarrollado sin determinar la naturaleza de la figura, como verdaderas cláusulas, originadas por la autonomía de la voluntad de las partes del contrato, o si se trata de privilegios conferidos e impuestos por el legislador, a la administración pública, como concreción del principio de legalidad. Este trabajo concluye que las cláusulas excepcionales al Derecho común, utilizadas en la actividad contractual de la administración pública, consisten en privilegios especiales que impone el legislador a las entidades estatales, dentro de la relación jurídica contractual, y que se contraponen a la esencia del verdadero concepto de cláusula y del principio de la autonomía de la voluntad.

    A limited autonomic neuropathy may underlie some unusual clinical syndromes, including the postural tachycardia syndrome, pseudo-obstruction syndrome, heat intolerance, and perhaps chronic fatigue syndrome. Antibodies to autonomic structures are common in diabetes, but their specificity is unknown. The presence of autonomic failure worsens prognosis in the diabetic state. Some autonomic neuropathies are treatable. Familial amyloid polyneuropathy may respond to liver transplantation. There are anecdotal reports of acute panautonomic neuropathy responding to intravenous gamma globulin. Orthostatic hypotension may respond to erythropoietin or midodrine.

    Self-sufficiency type houses are outlined. On condition that people gain a certain amount of income in relation with the society, they self-suffice under the given environment, allowing themselves to accept a minimum of industrial products with small environmental load. Ordinary supply from outside of fossil energy and materials which depend on it is minimized. Types are classified into three: energy, energy materials and perfect self-sufficiency. A study project for environment symbiotic houses is progressing which is planned by the Ministry of Construction and Institute of Building Energy Conservation and is invested by a private company. Its target is making a house for halving an environmental load by CO{sub 2}, for the purpose of creating the environment symbiotic house which is nice to and in harmony with the global environment and human beings. As a part of the studies on energy-saving and resource conservation on houses, introduced is a plan of an autonomous house at Izu-Atagawa. The passive method and high thermal-insulation are used for air conditioning, and hot spring water for hot water supply. Electric power is generated by hydroelectric power generation using mountain streams and by solar cells. Staple food is purchased, while subsidiary food is sufficed. 17 refs., 4 figs., 1 tab.

    Full Text Available UN EPISODIO DEL PENSAMIENTO FRANCÉS DE LA AUTONOMÍA Benjamin Constant y las idées très ingénieuses   Francisco Gelman Constantin Facultad de Filosofía y Letras, Universidad de Buenos Aires     Abstract – This paper attempts a consideration of the significance of Benjamin Constant’s aesthetic thoughts within the context of the history of the concept of “aesthetic autonomy”. With that in mind it reevaluates his transformation of the German tradition, by way of its binding to the social theory corresponding to the cultural and historical analysis of early French Romanticism. Taking the coinage of the expression “art for art’s sake” as a starting point, this paper reconstructs the whole of Constant’s thought-system, as well as its exchanges with some of his contemporaries –namely Mme. de Staël and Henry Crabb Robinson– in the means of understanding the proper reach of the conceptual novelties brought in by him, as can be seen from the standing point of Begriffsgeschichte. The paper deals not only with his postulates referring specifically to a negative relationship towards the mercantile society, but also with the analogies he establishes between art, love, religion and morality, while it furthermore examines his theory of social autonomy. The reflexive setting together of this different elements, assembled from his political essays, his journals, the novel Adolphe and other writings, brings to the light a general form of a thought of the autonomous, which explains the manner in which Constant understands aesthetic autonomy in particular, by way of his collaboration and dissent with his European colleagues.   Keywords: autonomy; Constant; art for art’s sake; Begriffsgeschichte; religion     Resumen – Este trabajo se propone reconsiderar la importancia de las reflexiones estéticas de Benjamin Constant en el contexto de la historia del concepto de autonomía estética.

The sample comprised 11 elderly individuals, disregarding their ADLs (age = 68.18 ± 5.19 years; body mass index (BMI = 28.89 ± 3.44 kg/m2 and not enrolled in physical exercise programs for at least 3 months. The subjects were submitted to a battery of 5 functional autonomy tests from the GDLAM protocol and blood collection to assess serum IGF-1 levels. Using Pearson’s correlation, we found a significant mean correlation coefficient (r between the 10 m walking test (10mW and IGF-1 (r = -0.690; p = 0.009 and mean correlation, but not significant between the putting on and removing a t-shirt test (PRTS and IGF-1 (r = -0.528 and between the general autonomy index (AI and IGF-1 (r = -0.417.

    Full Text Available While some of the recent literature addressing the sociology of work and organizations recognizes the role of workers’ agency, it always includes the concept of workers’ subjectivity as a contradictory and inconsistent “effect” of power relations. In contrast to this approach, using the analysis of eighteen interviews conducted with workers of an automotive multinational in Barcelona, it will be shown in this article the innovative, autonomous, logical and coherent character of the set of meanings guiding workers’ everyday actions. In this case study, the everyday actions of the workers are guided by a belief in the necessity of an ethical code of behavior. This code is composed of a set of congruent moral principles. The actions of resistance and commitment, presented by several authors as contradictory, appear being consistent with a set of ethical principles, and therefore, as value-rational actions.

    En parte de la literatura reciente sobre sociología del trabajo y de las organizaciones, el reconocimiento del papel de los obreros como agentes ha venido de la mano de una concepción de la subjetividad de los trabajadores como un “efecto” contradictorio e inconsistente de las relaciones de poder. Frente a esta concepción, y a partir del análisis de dieciocho entrevistas realizadas a trabajadores de una multinacional automovilística de Barcelona, se pondrá de manifiesto en este artículo el carácter innovador, autónomo, lógico y coherente del conjunto de los significados que guían las acciones cotidianas de los trabajadores. En el caso analizado, los trabajadores guían sus acciones cotidianas bajo la idea de la necesidad de respetar un código ético de comportamiento compuesto por una serie de principios morales bien trabados. Las acciones de compromiso y resistencia, que algunos autores presentan como contradictorias, aparecen aquí como acciones coherentes con una serie de principios éticos, y por tanto, como

This paper analyzes said process and the ensuing tension resulting from the High Courts of Cusco and Charcas having to solve procedural problems, but paying special attention to the debates and actors, especially lawyers, that constituted the Hispanic judicial culture during the Three-Year Liberal Period in the viceroyship of Peru, supposing that said reality extended to the national construction of Peru and Bolivia.A partir de 1820 y tras la invasión de San Martín, el sistema judicial peruano tuvo que adecuarse a la desaparición de facto de la Audiencia de Lima y al modelo diseñado por la Constitución de 1812 y el Reglamento de las Audiencias y Juzgados de primera instancia del 9 de octubre de 1812. El artículo analiza tal proceso y las tensiones generadas cuando las Audiencias Nacionales de Cusco y Charcas hubieron de resolver problemas de procedimiento, pero sobre todo se ahonda en los debates y actores, abogados fundamentalmente, que conformaron la cultura jurídica hispana durante el Trienio Liberal en el virreinato del Perú, asumiendo que tal realidad trascendió en la construcción nacional del Perú y Bolivia.

Métodos: Las LAT analizadas fueron no mortales con baja, de tipo mecánico y sobreesfuerzo, ocurridas en jornada en centro para empresas manufactureras y de la construcción. Se calculó el riesgo relativo ajustado por sexo, edad y tipo de contrato en cada una de las CC.AA. mediante la razón de LAT estandarizada, tomando como referencia las tasas de España, y estratificando según duración de la baja (menos de 16 días y más de 15 días. Resultados: El riesgo relativo ajustado de LAT según los diferentes tipos de accidentes analizados presenta una distribución heterogénea entre CC.AA. Murcia, Navarra, Baleares y País Vasco se encuentran generalmente entre las comunidades con riesgos más elevados, mientras que Castilla-León y Extremadura son las que tienen principalmente menores riesgos de sufrir una LAT. Conclusiones: La heterogeneidad en la incidencia de LAT entre CC.AA. persiste después de seleccionar una serie de formas de accidente específicas y ajustar por sexo, edad y tipo de contrato. Por ello sugerimos que, además de seguir analizando las condiciones de trabajo como explicación de esta heterogeneidad, se tengan en cuenta otras variables socioeconómicas al comparar las incidencias de LAT entre CC.AA.Objectives: Given the differences observed in previous studies with respect to occupational injury rates in Spain's autonomous communities, this study tested the homogeneity hypothesis of occupational injury for specific accident types and economic activity between 1994 and 2004.

    The objective of this study was to test the hierarchical model of motivation of Vallerand, using and experimental approximation. Sixty eight adolescents with ages between 14 and 16 years participated in the study. Two classes were assigned to a control (no choice group (n = 33 and other two to an experimental (choice group (n = 35. The intervention program was a didactic unit of six meetings with pre-test and post-test. Measures of contextual and situational self-determined motivation were employed. Results show that the experimental group showed higher post-intervention values in perception of autonomy, situational and contextual self-determined motivation. The implications related to the possibility of choosing the tasks to increase the perception of autonomy and the self-determined motivation in the physical education classes were discussed in the manuscript.

    The aim of this study was to assess padel facilities and its characteristics in the Autonomous Community of Extremadura according to the number of inhabitants. The totality of the padel courts built in this area was registered considering property, structure, the pavement surface and the location. The results show a total of 649 padel courts in Extremadura (409 in province of Badajoz and 240 in province of Cáceres. Public facilities account for the 50% of the total, however we found large differences between the provinces (44,25% in Badajoz and 57,92% in Cáceres. Likewise, similar density were observed between provinces but not when comparing districts. Regarding court profile, 93,05% had an artificial turf ground, 68,26% had a glass enclosure and 69,34 had an outdoor location.

    Full Text Available En el marco del vigésimo aniversario de la promulgación de la Ley 7600, y habiéndose cumplido ocho años desde la ratificación de la Convención sobre los Derechos de las Personas con Discapacidad por parte del Estado costarricense, se promulgó en agosto de 2016 la ley 9379 para la Promoción de la Autonomía Personal de las Personas con Discapacidad. Esta norma busca dotar de asistentes personales y apoyo legal a aquellos sujetos con diversidad funcional cuya situación económica no les permite acceder a tales servicios. Además, estatuye la anulación de los regímenes de “Interdicción”, “Insania” y “Nombramiento de Curador” dispuestos en los códices civiles y de familia. Así, la Ley 9379 aboga por la recuperación de la capacidad de actuar de estos individuos, con lo que recobran aquellos derechos personales que habían perdido con su inhabilitación. Entre tales prerrogativas está el derecho al sufragio activo, en razón de lo cual se manda a reinscribir al Padrón Electoral a quienes fueron segregados en cumplimiento de una sentencia civil.

  8. [Idiopathic autonomic neuropathy (pandysautonomia)].

    Jankowicz, E; Drozdowski, W; Pogumirski, J

    2001-01-01

    On the basis of current literature, clinical and neuropathologic features of idiopathic autonomic neuropathy is presented. Idiopathic autonomic neuropathy is a disease characterized by acute or subacute onset, monophasic course over a period of several years, it is often preceded by an infection. The spectrum of autonomic changes ranges from cholinergic or adrenergic dysfunction to pandysautonomia, leading to heterogeneity of its clinical features. Possible sympathetic system abnormalities found in autonomic neuropathy are: poor pupillary response to light in darkness, orthostatic hypotension leading to syncope, hypotension without compensatory tachycardia, ejaculation disturbances and vasomotor instability. Possible parasympathetic dysfunctions are: salivation and lacrimation disturbances, absent pupillary constriction to light and near gaze, gastrointestinal tract immobility and impairment of gastrointestinal function, atonic bladder with large residual volume, erectile impotence. Pandysautonomia is thought to result from an immune mediated mechanism and responds well to plasmaferesis and intravenous immunoglobin therapy leading to gradual, sometimes not full, recovery. Moreover in this article we pay attention to the clinical value of many tests like cardiovascular or pharmacological studies in the diagnosis of pandysautonomia and in differentiation of pre- and postganglionic changes. In order to diagnose idiopathic autonomic neuropathy one has to rule out a large number of diseases with autonomic dysfunction e.g.: diabetes, malignant neoplasms, acute intermittent porphyria, Shy-Drager syndrome, Riley-Day's dysautonomia, Parkinson's disease, amyloidosis and others.

  9. La responsabilidad contractual por los riesgos previsibles, entre la autonomía de la voluntad privada y la rigurosidad de las normas de contratación pública

    2016-12-01

    Full Text Available Los riesgos contractuales previsibles carecen de reglas específicas en el régimen de “derecho común”. Con todo, la autonomía de la voluntad privada usualmente resuelve este vacío por medio de disposiciones contractuales accesorias. Con todo, en el derecho público de la contratación estatal, la rigidez del proceso precontractual impone deberes de tipificación, estimación y asignación de riesgos que no parecerían estar definidos por el régimen jurídico pertinente. En este artículo se argumenta que, debido a la dispersión normativa de la contratación administrativa, el régimen jurídico de los riesgos previsibles se encuentra indeterminado, muy a pesar de la inflexibilidad normativa de la etapa de diseño contractual.

    The global movement of people and goods has increased the risk of biosecurity threats and their potential to incur large economic, social, and environmental costs. Conventional manual biosecurity surveillance methods are limited by their scalability in space and time. This article focuses on autonomous surveillance systems, comprising sensor networks, robots, and intelligent algorithms, and their applicability to biosecurity threats. We discuss the spatial and temporal attributes of autonomous surveillance technologies and map them to three broad categories of biosecurity threat: (i) vector-borne diseases; (ii) plant pests; and (iii) aquatic pests. Our discussion reveals a broad range of opportunities to serve biosecurity needs through autonomous surveillance. Crown Copyright © 2015. Published by Elsevier Ltd. All rights reserved.

  2. Nature's Autonomous Oscillators

    Science.gov (United States)

    Mayr, H. G.; Yee, J.-H.; Mayr, M.; Schnetzler, R.

    2012-01-01

    Nonlinearity is required to produce autonomous oscillations without external time dependent source, and an example is the pendulum clock. The escapement mechanism of the clock imparts an impulse for each swing direction, which keeps the pendulum oscillating at the resonance frequency. Among nature's observed autonomous oscillators, examples are the quasi-biennial oscillation and bimonthly oscillation of the Earth atmosphere, and the 22-year solar oscillation. The oscillations have been simulated in numerical models without external time dependent source, and in Section 2 we summarize the results. Specifically, we shall discuss the nonlinearities that are involved in generating the oscillations, and the processes that produce the periodicities. In biology, insects have flight muscles, which function autonomously with wing frequencies that far exceed the animals' neural capacity; Stretch-activation of muscle contraction is the mechanism that produces the high frequency oscillation of insect flight, discussed in Section 3. The same mechanism is also invoked to explain the functioning of the cardiac muscle. In Section 4, we present a tutorial review of the cardio-vascular system, heart anatomy, and muscle cell physiology, leading up to Starling's Law of the Heart, which supports our notion that the human heart is also a nonlinear oscillator. In Section 5, we offer a broad perspective of the tenuous links between the fluid dynamical oscillators and the human heart physiology.

    Scott, P A

    1998-12-01

    The structures and contexts within which nurses work results in the moral agency and moral autonomy of the nurse being compromised. This claim results from a confusion of (1) the concept of autonomy with those of freedom and independence; and (2) a confusion of the notion of moral autonomy with that of autonomous professional practice. The drawing of appropriate distinctions allows clarification of the relevant concepts. It also underlines the responsibility of practitioners to recognize the moral dimension of their practice, and the moral implications of their actions, as they attempt to meet the health care needs of their patients and develop practice professionally.

    2013-03-01

    Many generalized tonic-clonic seizures are accompanied by profound autonomic changes. However, autonomic seizures and autonomic status epilepticus can also be seen with specific electroclinical syndromes (Panayiotopoulos syndrome), etiologies, and localizations. Such autonomic symptoms may impact cardiorespiratory function. While it is likely that several factors contribute to SUDEP, further study of both ictal respiratory and cardiac changes and underlying neuroanatomical mechanisms involved in autonomic seizure semiology are likely to provide important data to improve our understanding of the pathophysiology of this devastating condition. This paper will review the association between autonomic symptoms and epileptic seizures and will highlight the work of three young investigators. Drs. Lisa Bateman and Brian Moseley will review their work on cardiorespiratory effects of recorded seizures and how this assists in our understanding of SUDEP. Dr. John Millichap will review autonomic seizures and autonomic dysfunctions related to childhood epilepsy and will discuss the importance of expanded research efforts in this field.

  11. Towards autonomous vehicular clouds

    Stephan Olariu

    2011-09-01

    Full Text Available The dawn of the 21st century has seen a growing interest in vehicular networking and its myriad potential applications. The initial view of practitioners and researchers was that radio-equipped vehicles could keep the drivers informed about potential safety risks and increase their awareness of road conditions. The view then expanded to include access to the Internet and associated services. This position paper proposes and promotes a novel and more comprehensive vision namely, that advances in vehicular networks, embedded devices and cloud computing will enable the formation of autonomous clouds of vehicular computing, communication, sensing, power and physical resources. Hence, we coin the term, autonomous vehicular clouds (AVCs. A key feature distinguishing AVCs from conventional cloud computing is that mobile AVC resources can be pooled dynamically to serve authorized users and to enable autonomy in real-time service sharing and management on terrestrial, aerial, or aquatic pathways or theaters of operations. In addition to general-purpose AVCs, we also envision the emergence of specialized AVCs such as mobile analytics laboratories. Furthermore, we envision that the integration of AVCs with ubiquitous smart infrastructures including intelligent transportation systems, smart cities and smart electric power grids will have an enormous societal impact enabling ubiquitous utility cyber-physical services at the right place, right time and with right-sized resources.

    2004-01-01

    NASA's Strategic Plan for the Aerospace Technology Enterprise includes ambitious objectives focused on affordable air travel, reduced emissions, and expanded aviation-system capacity. NASA Dryden Flight Research Center, in cooperation with NASA Ames Research Center, the Boeing Company, and the University of California, Los Angeles, has embarked on an autonomous-formation-flight project that promises to make significant strides towards these goals. For millions of years, birds have taken advantage of the aerodynamic benefit of flying in formation. The traditional "V" formation flown by many species of birds (including gulls, pelicans, and geese) enables each of the trailing birds to fly in the upwash flow field that exists just outboard of the bird immediately ahead in the formation. The result for each trailing bird is a decrease in induced drag and thus a reduction in the energy needed to maintain a given speed. Hence, for migratory birds, formation flight extends the range of the system of birds over the range of birds flying solo. The Autonomous Formation Flight (AFF) Project is seeking to extend this symbiotic relationship to aircraft.

Multiple craft launched from an orbiting mother ship could provide near-global coverage. Each craft is envisioned to fly at about 1 km above the surface and measure atmospheric composition, pressure and temperature, map surface topography, and remotely penetrate the near subsurface looking for water (ice) and perhaps evidence of life. Data collected are relayed to Earth via the orbiting mother ship. Near surface guidance and control capability is an adaptation of current cruise missile technology. A solar powered aircraft designed to fly in the low temperature, low density, carbon dioxide Martian atmosphere near the surface appears feasible.

In this article, we propose a fully distributed and scalable solution to the interference management problem......Low-power base stations such as e.g. Femto-cells are one of the candidates for high data rate provisioning in local areas, such as residences, apartment complexes, business offices and outdoor hotspot scenarios. Unfortunately, the benefits are not without new challenges in terms of interference...... in local areas, basing our study case on LTE-Advanced.

    La Constitución española reconoce la autonomía universitaria como derecho social, para que las universidades alcancen eficazmente sus fines de servicio a la sociedad a través de la adecuada gestión del conocimiento. El panorama actual, universitario y social, revela grandes carencias para garantizar una verdadera autonomía universitaria que debe apoyarse, previamente, en una planificación del modelo de sociedad del conocimiento requerido para alcanzar autonomía social.

    High profile breaches have occurred across numerous information systems. One area where attacks are particularly problematic is autonomous control systems. This paper considers the aerospace information system, focusing on elements that interact with autonomous control systems (e.g., onboard UAVs). It discusses the trust placed in the autonomous systems and supporting systems (e.g., navigational aids) and how this trust can be validated. Approaches to remotely detect the UAV compromise, without relying on the onboard software (on a potentially compromised system) as part of the process are discussed. How different levels of autonomy (task-based, goal-based, mission-based) impact this remote characterization is considered.

  4. La aparente impenetrabilidad de la autonomía universitaria

    2017-01-01

    Full Text Available El objetivo de este documento es explorar la perspectiva de la autonomía universitaria a la luz de los fines y particularidad de la universidad. La autonomía universitaria es un asunto que, desde variadas perspectivas, es determinante en la manera en que se comprende, realiza y proyecta el quehacer educativo. Está determinada por el contexto socio-cultural y político en que se pretende llevar a cabo; actualmente, las condiciones impuestas por el modelo económico capitalista hacen que su relación con la libertad sea paradójica: centrada en la limitación y negación, la libertad de unos está vinculada con la no-libertad de otros. La autonomía está en íntima relación con el entorno social, político y económico, expresa una manera de estar en el mundo, responde a una ética basada en principios y a una perspectiva de organización política; se concreta en maneras de participación social y educativa directa y decisoria. La crisis de la autonomía también se comunica con el ámbito de la salud, donde la definición del conocimiento, de las prácticas, de los principios éticos y de las relaciones interpersonales se han ido centrando en el logro de los fines e intereses particulares; las ciencias de la salud están participando de la dinámica de organización de la vida desde los valores morales y principios éticos del liberalismo, el individualismo y la ganancia. Explorar alternativas para la construcción de la autonomía universitaria implica adentrarse en el reconocimiento y puesta en práctica de una formación desde el humanismo y poner en cuestión la excelencia académica que está de espalda a la realidad de las comunidades y realidades latinoamericanas.

    Introducción

    El estudio del sistema nervioso considera entre múltiples conexiones, aquéllas de carácter bioquímico que se median a través de sustancias elaboradas por las neuronas y que reciben la denominación de neurotransmisores’, dichas sustancias se vierten en las zonas de resquicio neuromuscular, neuroneuronal o neuroglandular, para modificar las condiciones de membrana y permitir la continuidad de los potenciales de acción (por creación de nuevos potenciales en las células subsiguientes, de la neurona hacia el órgano blanco.

    La integridad de los diversos elementos de la “zona de unión funcional” o sinapsis, asegura la adecuada comunicación entre el sistema nervioso y la mayoría de los elementos restantes del organismo humano.

    Las alteraciones de los elementos de las sinapsis, conllevan a la génesis de estados variables fisiológicos y patológicos somáticos, psicosomáticos o psíquicos, inconsecuentes con el estado de homeostasis.

    Las moléculas que se vierten en las hendiduras sinápticas, sirven, por tanto, de transductoras para efectos elementales (como los reflejos y en las estrategias complejas (como los de la actividad intelectual.

    Antecedentes

    Ya desde los tiempos de Galeno, se sabía que los nervios eran los responsables de la rápida comunicación entre el cuerpo y el cerebro; el estudio de las sinapsis nos remonta de manera indirecta a
    1791, fecha en la que Luigi Galvani, descubrió en sus experimentos con ancas de ranas, que entre los eventos eléctricos y los ocurridos en los nervios, existía una relación evidente (28,37,45’, los experimentos de Galvani se han refinado con el paso del tiempo, en nuestro siglo por ejemplo, el desarrollo del osciloscopio de rayos catódicos combinado con un amplificador potente, ha permitido medir las débiles y variables corrientes bioeléctricas de los

    We present a new algorithm, named Autonomous Gaussian Decomposition (AGD), for automatically decomposing spectra into Gaussian components. AGD uses derivative spectroscopy and machine learning to provide optimized guesses for the number of Gaussian components in the data, and also their locations, widths, and amplitudes. We test AGD and find that it produces results comparable to human-derived solutions on 21 cm absorption spectra from the 21 cm SPectral line Observations of Neutral Gas with the EVLA (21-SPONGE) survey. We use AGD with Monte Carlo methods to derive the H i line completeness as a function of peak optical depth and velocity width for the 21-SPONGE data, and also show that the results of AGD are stable against varying observational noise intensity. The autonomy and computational efficiency of the method over traditional manual Gaussian fits allow for truly unbiased comparisons between observations and simulations, and for the ability to scale up and interpret the very large data volumes from the upcoming Square Kilometer Array and pathfinder telescopes

    2010-11-01

    We seek to explore if the swimming of paramecium has an underlying autonomic mechanism. Such robotic elements may be useful in capturing the disturbance field in an environment in real time. Experimental evidence is emerging that motion control neurons of other animals may be present in paramecium as well. The limit cycle determined using analog simulation of the coupled nonlinear oscillators of olivo-cerebellar dynamics (ieee joe 33, 563-578, 2008) agrees with the tracks of the cilium of a biological paramecium. A 4-motor apparatus has been built that reproduces the kinematics of the cilium motion. The motion of the biological cilium has been analyzed and compared with the results of the finite element modeling of forces on a cilium. The modeling equates applied torque at the base of the cilium with drag, the cilium stiffness being phase dependent. A low friction pendulum apparatus with a multiplicity of electromagnetic actuators is being built for verifying the maps of the attractor basin computed using the olivo-cerebellar dynamics for different initial conditions.

    With much higher levels of distributed energy resources - variable generation, energy storage, and controllable loads just to mention a few - being deployed into power systems, the data deluge from pervasive metering of energy grids, and the shaping of multi-level ancillary-service markets, current frameworks to monitoring, controlling, and optimizing large-scale energy systems are becoming increasingly inadequate. This position paper outlines the concept of 'Autonomous Energy Grids' (AEGs) - systems that are supported by a scalable, reconfigurable, and self-organizing information and control infrastructure, can be extremely secure and resilient (self-healing), and self-optimize themselves in real-time for economic and reliable performance while systematically integrating energy in all forms. AEGs rely on scalable, self-configuring cellular building blocks that ensure that each 'cell' can self-optimize when isolated from a larger grid as well as partaking in the optimal operation of a larger grid when interconnected. To realize this vision, this paper describes the concepts and key research directions in the broad domains of optimization theory, control theory, big-data analytics, and complex system modeling that will be necessary to realize the AEG vision.

    The mechanisms of dysautonomic disturbances are varied and mostly acquired. They can result from lesions of sympathetic or parasympathetic vegetative fibers located in the peripheral contingent, or in the somatic contingent by demyelination or axonal loss; or more rarely by cellular bodies in the sympathetic or parasympathetic ganglia. Several chronic peripheral neuropathies can be associated with dysautonomia. Only some causes need to be known because they can be clinically significant. Dysautonomia may be seen during chronic acquired neuropathies but also acute or subacute ones. The most frequent cause in the world is the dysautonomia of the diabetes; it affects all the systems; the cardiovascular dysfunction has an impact on the prognosis for survival when it is severe. Hereditary autonomic neuropathies are rare; they can declare themselves very early during the Riley-Day syndrome or very late during amyloid polyneuropathies due to transthyretin gene mutation. The diagnosis can be confirmed by molecular biology. The dysautonomia is frequent and often severe. These neuropathies justify symptomatic treatment to improve quality of life. For some of them, a specific treatment can be proposed to treat the causal affection to try to stop the progression of the disease. Copyright © 2012. Published by Elsevier Masson SAS.

  13. Autonomous power system: Integrated scheduling

    Ringer, Mark J.

    1992-01-01

    The Autonomous Power System (APS) project at NASA Lewis Research Center is designed to demonstrate the abilities of integrated intelligent diagnosis, control and scheduling techniques to space power distribution hardware. The project consists of three elements: the Autonomous Power Expert System (APEX) for fault diagnosis, isolation, and recovery (FDIR), the Autonomous Intelligent Power Scheduler (AIPS) to determine system configuration, and power hardware (Brassboard) to simulate a space-based power system. Faults can be introduced into the Brassboard and in turn, be diagnosed and corrected by APEX and AIPS. The Autonomous Intelligent Power Scheduler controls the execution of loads attached to the Brassboard. Each load must be executed in a manner that efficiently utilizes available power and satisfies all load, resource, and temporal constraints. In the case of a fault situation on the Brassboard, AIPS dynamically modifies the existing schedule in order to resume efficient operation conditions. A database is kept of the power demand, temporal modifiers, priority of each load, and the power level of each source. AIPS uses a set of heuristic rules to assign start times and resources to each load based on load and resource constraints. A simple improvement engine based upon these heuristics is also available to improve the schedule efficiency. This paper describes the operation of the Autonomous Intelligent Power Scheduler as a single entity, as well as its integration with APEX and the Brassboard. Future plans are discussed for the growth of the Autonomous Intelligent Power Scheduler.

  15. Autonomous Byte Stream Randomizer

    2013-01-01

    Net-centric networking environments are often faced with limited resources and must utilize bandwidth as efficiently as possible. In networking environments that span wide areas, the data transmission has to be efficient without any redundant or exuberant metadata. The Autonomous Byte Stream Randomizer software provides an extra level of security on top of existing data encryption methods. Randomizing the data s byte stream adds an extra layer to existing data protection methods, thus making it harder for an attacker to decrypt protected data. Based on a generated crypto-graphically secure random seed, a random sequence of numbers is used to intelligently and efficiently swap the organization of bytes in data using the unbiased and memory-efficient in-place Fisher-Yates shuffle method. Swapping bytes and reorganizing the crucial structure of the byte data renders the data file unreadable and leaves the data in a deconstructed state. This deconstruction adds an extra level of security requiring the byte stream to be reconstructed with the random seed in order to be readable. Once the data byte stream has been randomized, the software enables the data to be distributed to N nodes in an environment. Each piece of the data in randomized and distributed form is a separate entity unreadable on its own right, but when combined with all N pieces, is able to be reconstructed back to one. Reconstruction requires possession of the key used for randomizing the bytes, leading to the generation of the same cryptographically secure random sequence of numbers used to randomize the data. This software is a cornerstone capability possessing the ability to generate the same cryptographically secure sequence on different machines and time intervals, thus allowing this software to be used more heavily in net-centric environments where data transfer bandwidth is limited.

    Autonomous navigation of Satellite and constellation has series of benefits, such as to reduce operation cost and ground station workload, to avoid the event of crises of war and natural disaster, to increase spacecraft autonomy, and so on. Autonomous navigation satellite is independent of ground station support. Many systems are developed for autonomous navigation of satellite in the past 20 years. Along them American MANS (Microcosm Autonomous Navigation System) [1] of Microcosm Inc. and ERADS [2] [3] (Earth Reference Attitude Determination System) of Honeywell Inc. are well known. The systems anticipate a series of good features of autonomous navigation and aim low cost, integrated structure, low power consumption and compact layout. The ERADS is an integrated small 3-axis attitude sensor system with low cost and small volume. It has the Earth center measurement accuracy higher than the common IR sensor because the detected ultraviolet radiation zone of the atmosphere has a brightness gradient larger than that of the IR zone. But the ERADS is still a complex system because it has to eliminate many problems such as making of the sapphire sphere lens, birefringence effect of sapphire, high precision image transfer optical fiber flattener, ultraviolet intensifier noise, and so on. The marginal sphere FOV of the sphere lens of the ERADS is used to star imaging that may be bring some disadvantages., i.e. , the image energy and attitude measurements accuracy may be reduced due to the tilt image acceptance end of the fiber flattener in the FOV. Besides Japan, Germany and Russia developed visible earth sensor for GEO [4] [5]. Do we have a way to develop a cheaper/easier and more accurate autonomous navigation system that can be used to all LEO spacecraft, especially, to LEO small and micro satellites? To return this problem we provide a new type of the system—CANS (Compact Autonomous Navigation System) [6].

    2016-08-01

    This thesis investigates autonomous landing of a micro air vehicle (MAV) on a nonstationary ground platform. Unmanned aerial vehicles (UAVs) and micro air vehicles (MAVs) are becoming every day more ubiquitous. Nonetheless, many applications still require specialized human pilots or supervisors. Current research is focusing on augmenting the scope of tasks that these vehicles are able to accomplish autonomously. Precise autonomous landing on moving platforms is essential for self-deployment and recovery of MAVs, but it remains a challenging task for both autonomous and piloted vehicles. Model Predictive Control (MPC) is a widely used and effective scheme to control constrained systems. One of its variants, output-feedback tube-based MPC, ensures robust stability for systems with bounded disturbances under system state reconstruction. This thesis proposes a MAV control strategy based on this variant of MPC to perform rapid and precise autonomous landing on moving targets whose nominal (uncommitted) trajectory and velocity are slowly varying. The proposed approach is demonstrated on an experimental setup.

    Full Text Available Autonomous weapons would have the capacity to select and attack targets without direct human input. One important objection to the introduction of such weapons is that they will make it more difficult to identify and hold accountable those responsible for undesirable outcomes such as mission failures and civilian casualties. I hypothesize that individuals can modify their attribution of responsibility in predicable ways to accommodate this new technology. The results of a survey experiment are consistent with this; subjects continue to find responsible and hold accountable political and military leaders when autonomous weapons are used, but also attribute responsibility to the designers and programmers of such weapons.

    1991-01-01

    Full Text Available The role of the autonomic nervous system in circulatory regulation of the splanchnic organs (stomach, small intestine, colon, liver, pancreas and spleen is reviewed. In general, the sympathetic nervous system is primarily involved in vasoconstriction, while the parasympathetic contributes to vasodilation. Vasoconstriction in the splanchnic circulation appears to be mediated by alpha-2 receptors and vasodilation by activation of primary afferent nerves with subsequent release of vasodilatory peptides, or by stimulation of beta-adrenergic receptors. As well, an important function of the autonomic nervous system is to provide a mechanism by which splanchnic vascular reserve can be mobilized during stress to maintain overall cardiovascular homeostasis.

    La noción de autonomía ocupa un lugar muy importante en la filosofía moral de Kant, si bien éste no es el de proporcionar el fundamento de la validez de las exigencias que la moralidad dirige a un ser como el hombre. Según Kant, sólo si obro con arreglo a la ley moral merece ese obrar ser considerado autónomo: conducta autónoma y conducta moralmente valiosa son nociones equivalentes, luego en la primera no puede residir el fundamento de la segunda. Por otra parte, el hecho de que la ley moral...

    Working on the ACLO (Autonomous Cryogenics Loading Operations) project I have had the opportunity to add functionality to the physics simulation software known as KATE (Knowledgebase Autonomous Test Engineer), create a new application allowing WYSIWYG (what-you-see-is-what-you-get) creation of KATE schematic files and begin a preliminary design and implementation of a new subsystem that will provide vision services on the IHM (Integrated Health Management) bus. The functionality I added to KATE over the past few months includes a dynamic visual representation of the fluid height in a pipe based on number of gallons of fluid in the pipe and implementing the IHM bus connection within KATE. I also fixed a broken feature in the system called the Browser Display, implemented many bug fixes and made changes to the GUI (Graphical User Interface).

  2. Morphologic Changes in Autonomic Nerves in Diabetic Autonomic Neuropathy

    Full Text Available Diabetic neuropathy is one of the major complications of diabetes, and it increases morbidity and mortality in patients with both type 1 diabetes mellitus (T1DM and type 2 diabetes mellitus (T2DM. Because the autonomic nervous system, for example, parasympathetic axons, has a diffuse and wide distribution, we do not know the morphological changes that occur in autonomic neural control and their exact mechanisms in diabetic patients with diabetic autonomic neuropathy (DAN. Although the prevalence of sympathetic and parasympathetic neuropathy is similar in T1DM versus T2DM patients, sympathetic nerve function correlates with parasympathetic neuropathy only in T1DM patients. The explanation for these discrepancies might be that parasympathetic nerve function was more severely affected among T2DM patients. As parasympathetic nerve damage seems to be more advanced than sympathetic nerve damage, it might be that parasympathetic neuropathy precedes sympathetic neuropathy in T2DM, which was Ewing's concept. This could be explained by the intrinsic morphologic difference. Therefore, the morphological changes in the sympathetic and parasympathetic nerves of involved organs in T1DM and T2DM patients who have DAN should be evaluated. In this review, evaluation methods for morphological changes in the epidermal nerves of skin, and the intrinsic nerves of the stomach will be discussed.

    Knowledge of the physiology underlying the autonomic nervous system is pivotal for understanding autonomic dysfunction in clinical practice. Autonomic dysfunction may result from primary modifications of the autonomic nervous system or be secondary to a wide range of diseases that cause severe morbidity and mortality. Together with a detailed history and physical examination, laboratory assessment of autonomic function is essential for the analysis of various clinical conditions and the establishment of effective, personalized and precise therapeutic schemes.

    2014-12-01

    Full Text Available Diabetic autonomic neuropathy (DAN is a serious and common complication of diabetes, often overlooked and misdiagnosed. It is a systemic-wide disorder that may be asymptomatic in the early stages. The most studied and clinically important form of DAN is cardiovascular autonomic neuropathy (CAN defined as the impairment of autonomic control of the cardiovascular system in patients with diabetes after exclusion of other causes. The reported prevalence of DAN varies widely depending on inconsistent definition, different diagnostic method, different patient cohorts studied. The pathogenesis is still unclear and probably multifactorial. Once DAN becomes clinically evident, no form of therapy has been identified which can effectively stop or reverse it. Prevention strategies are based on strict glycemic control with intensive insulin treatment, multifactorial intervention and lifestyle modification including control of hypertension, dyslipidemia, stop smoking, weight loss and adequate physical exercise. The present review summarizes the latest knowledge regarding clinical presentation, epidemiology, pathogenesis and management of DAN, with some mention to childhood and adolescent population.

    2010-04-01

    CMMAD is a risk reduction effort for the AMDS program. As part of CMMAD, multiple instances of semi autonomous robotic mine detection systems were created. Each instance consists of a robotic vehicle equipped with sensors required for navigation and marking, a countermine sensors and a number of integrated software packages which provide for real time processing of the countermine sensor data as well as integrated control of the robotic vehicle, the sensor actuator and the sensor. These systems were used to investigate critical interest functions (CIF) related to countermine robotic systems. To address the autonomy CIF, the INL developed RIK was extended to allow for interaction with a mine sensor processing code (MSPC). In limited field testing this system performed well in detecting, marking and avoiding both AT and AP mines. Based on the results of the CMMAD investigation we conclude that autonomous robotic mine detection is feasible. In addition, CMMAD contributed critical technical advances with regard to sensing, data processing and sensor manipulation, which will advance the performance of future fieldable systems. As a result, no substantial technical barriers exist which preclude – from an autonomous robotic perspective – the rapid development and deployment of fieldable systems.

    2007-01-01

    Full Text Available La autonomía es un principio moderno de la bioética; éste surge como consecuencia de un concepto de ser humano que respeta la libertad personal. En este momento de la historia en el desarrollo de la ciencia es vertiginoso es preciso sentar las bases para el desarrollo de una escala de valores en la que esté implícito el respeto por la dignidad humana y la libre decisión del paciente en cualquier grado de enfermedad. Para el profesional de enfermería se convierte en una alta responsabilidad social y humana inherente a la esencia de su ejercicio velar por la capacidad de decisión de las personas, y el derecho a que se respete su voluntad en todos los momentos, incluidos los momentos críticos de su vida. No obstante, aunque el sistema impulse lo contrario, es preciso trabajar en pro de la autonomía y la autodeterminación del ser respetando sus derechos. Por ello se requiere que en los procesos formativos, docentes y estudiantes trabajen en forma conjunta valores, principios y actitudes éticas que faciliten el abordaje del cuidado brindado, y desde esta perspectiva se tenga en cuenta la libertad para la toma de decisiones por parte del paciente.

Se trata de una iniciativa legislativa dirigida a modernizar y coordinar la política exterior de España que ha sido promovida por el actual gobierno del Partido Popular y que ha sido aprobada con el único respaldo de su grupo parlamentario que cuenta con mayoría absoluta en las Cortes. El principal objetivo perseguido por la ley, garantizar el principio de unidad de acción del Estado, ha situado a las Comunidades Autónomas en el centro del debate político. La mayor parte de las críticas efectuadas por los grupos de oposición se han centrado en este aspecto destacando su carácter “recentralizador”. Cabe discutir, por tanto, si la ley recorta las competencias autonómicas en materia exterior.

    To improve operational availability (the proportion of time that a telescope is able to accomplish what a visiting observer wants at the time the observation is scheduled), response time to faults must be minimized. One way this can be accomplished is by characterizing the relationships and interdependencies between components in a control system, developing algorithms to identify the root cause of a problem, and capturing expert knowledge of a system to simplify the process of troubleshooting. Results from a prototype development are explained, along with deployment issues. Implications for the future, such as effective knowledge representation and management, and learning processes which integrate autonomous and interactive components, are discussed.

    When studying fluid dynamics, especially in a turbulent regime, it is crucial to estimate the number of active degrees of freedom or of localized structures in the system. The topological entropy quantifies the exponential growth of the number of `distinct` orbits in a dynamical system as a function of their length, in the infinite spatial resolution limit. Here, I illustrate a novel method for its evaluation, which extends beyond maps and is applicable to any system, including autonomous flows: these are characterized by lack of a definite absolute time scale for the orbit lengths.

    We developed, tested, and now operate a civilian biological defense capability that continuously monitors the air for biological threat agents. The Autonomous Pathogen Detection System (APDS) collects, prepares, reads, analyzes, and reports results of multiplexed immunoassays and multiplexed PCR assays using Luminex{copyright} xMAP technology and flow cytometer. The mission we conduct is particularly demanding: continuous monitoring, multiple threat agents, high sensitivity, challenging environments, and ultimately extremely low false positive rates. Here, we introduce the mission requirements and metrics, show the system engineering and analysis framework, and describe the progress to date including early development and current status.

    Maria Gabriela Zurita-Benavides

    Full Text Available Resumen Las prácticas agrícolas dan información que revelan la relación entre un grupo humano y el bosque. Este estudio describe y analiza el itinerario agrícola considerando que las acciones materializan las principales características socioculturales de los waorani de la Amazonia ecuatoriana: libertad de acción y autonomía personal. La observación participante y la identificación de las plantas cultivadas en dos aldeas waorani durante quince meses de investigación permitieron determinar los aspectos socioculturales y ecológicos del sistema de roza-tumba-pudre. La práctica de este sistema agrícola no es común en otras partes del mundo, siendo relativamente poco conocida y desvalorizada debido a su productividad. El presente artículo presenta un caso de estudio del sistema de roza-tumba-pudre inscrito en la cosmovisión cultural, prácticas agrícolas y representaciones que se mantienen a pesar del contacto con otros tipos de agriculturas. Los waorani continúan realizando estas prácticas agrícolas porque están en concordancia con su propia concepción de las dinámicas de transformación de los recursos naturales.

    Full Text Available Tomando como punto de partida el enunciado filosófico del cual emerge la idea de autonomía universitaria, señalamos que su conquista está enmarcada en un proceso de larga duración, desde sus orígenes remotos, hasta la actualidad. En dicho proceso, el desenvolvimiento histórico de la universidad muestra las tensiones que han existido entre la autonomía de la comunidad universitaria y los poderes públicos que pugnan por controlarla. Entre dichas tensiones figura la política de subsidio a la demanda, en el marco del debilitamiento del Estado, y el avance de la mercantilización, tal como ha ocurrido en América Latina y en los Estados Unidos en las últimas décadas. Incorporamos la noción de bien público para ir más allá del dualismo simplista entre lo público y lo privado, dominante en la visión del Gobierno, en la que subyace la idea de que las universidades públicas son ineficientes, porque gozan de autonomía y no tienen disciplina de mercado. Nuestra hipótesis es que hay una relación directa entre el recorte sistemático de la autonomía y la caída de la calidad de la educación superior pública, legitimada en la composición política de los Consejos Superiores, en los que tienen primacía el gobierno y los sectores externos, convirtiendo a la autonomía universitaria en heteronomía. En esas condiciones el Estado mide y controla la calidad de la educación, pero no invierte en ella. Sugerimos que la clave para alcanzar una senda de desarrollo educativo superior no está tanto en las condiciones económicas y sociales de un país, ni en las reformas puntuales elegidas, sino en la permanencia en el tiempo de un conjunto de valores comunes que hagan de quienes realizan la actividad educativa (estudiantes, profesores, administradores, familias los mejores evaluadores de su propio desempeño, en procesos en los que todos contribuyen a un propósito público que supera los intereses privados e individuales.

  3. Structured control for autonomous robots

    1994-01-01

    To operate in rich, dynamic environments, autonomous robots must be able to effectively utilize and coordinate their limited physical and occupational resources. As complexity increases, it becomes necessary to impose explicit constraints on the control of planning, perception, and action to ensure that unwanted interactions between behaviors do not occur. This paper advocates developing complex robot systems by layering reactive behaviors onto deliberative components. In this structured control approach, the deliberative components handle normal situations and the reactive behaviors, which are explicitly constrained as to when and how they are activated, handle exceptional situations. The Task Control Architecture (TCA) has been developed to support this approach. TCA provides an integrated set of control constructs useful for implementing deliberative and reactive behaviors. The control constructs facilitate modular and evolutionary system development: they are used to integrate and coordinate planning, perception, and execution, and to incrementally improve the efficiency and robustness of the robot systems. To date, TCA has been used in implementing a half-dozen mobile robot systems, including an autonomous six-legged rover and indoor mobile manipulator

    In this paper, an automatic robotic inspector for tunnel assessment is presented. The proposed platform is able to autonomously navigate within the civil infrastructures, grab stereo images and process/analyse them, in order to identify defect types. At first, there is the crack detection via deep learning approaches. Then, a detailed 3D model of the cracked area is created, utilizing photogrammetric methods. Finally, a laser profiling of the tunnel's lining, for a narrow region close to detected crack is performed; allowing for the deduction of potential deformations. The robotic platform consists of an autonomous mobile vehicle; a crane arm, guided by the computer vision-based crack detector, carrying ultrasound sensors, the stereo cameras and the laser scanner. Visual inspection is based on convolutional neural networks, which support the creation of high-level discriminative features for complex non-linear pattern classification. Then, real-time 3D information is accurately calculated and the crack position and orientation is passed to the robotic platform. The entire system has been evaluated in railway and road tunnels, i.e. in Egnatia Highway and London underground infrastructure.

    Nowadays, there are various types of robot have been invented for multiple purposes. The robots have the special characteristic that surpass the human ability and could operate in extreme environment which human cannot endure. In this paper, an autonomous robot is built to imitate the characteristic of a human cutting grass. A Field Programmable Gate Array (FPGA) is used to control the movements where all data and information would be processed. Very High Speed Integrated Circuit (VHSIC) Hardware Description Language (VHDL) is used to describe the hardware using Quartus II software. This robot has the ability of avoiding obstacle using ultrasonic sensor. This robot used two DC motors for its movement. It could include moving forward, backward, and turning left and right. The movement or the path of the automatic lawn mower is based on a path planning technique. Four Global Positioning System (GPS) plot are set to create a boundary. This to ensure that the lawn mower operates within the area given by user. Every action of the lawn mower is controlled by the FPGA DE' Board Cyclone II with the help of the sensor. Furthermore, Sketch Up software was used to design the structure of the lawn mower. The autonomous lawn mower was able to operate efficiently and smoothly return to coordinated paths after passing the obstacle. It uses 25% of total pins available on the board and 31% of total Digital Signal Processing (DSP) blocks.

    The Autonomous Power System (APS) project at NASA Lewis Research Center is designed to demonstrate the abilities of integrated intelligent diagnosis, control, and scheduling techniques to space power distribution hardware. Knowledge-based software provides a robust method of control for highly complex space-based power systems that conventional methods do not allow. The project consists of three elements: the Autonomous Power Expert System (APEX) for fault diagnosis and control, the Autonomous Intelligent Power Scheduler (AIPS) to determine system configuration, and power hardware (Brassboard) to simulate a space based power system. The operation of the Autonomous Power System as a whole is described and the responsibilities of the three elements - APEX, AIPS, and Brassboard - are characterized. A discussion of the methodologies used in each element is provided. Future plans are discussed for the growth of the Autonomous Power System.

    Full Text Available Cardiovascular autonomic neuropathy is frequently observed in patients with diabetes mellitus and encompasses damage to the autonomic nerve fibers, resulting in abnormalities in heart rate control and vascular dynamics. There is an increased mortality and morbidity rate among these patients. A series of cardiovascular reflex tests known as Ewing's battery tests are used for diagnosis cardiac autonomic neuropathy and provide valuable information to the clinical assessment of these patients. As anesthesia has a major influence on perioperative autonomic function, the interplay between cardiovascular autonomic neuropathy and anesthesia may result in unexpected haemodynamic instability during surgery and postoperative recovery. A comprehensive preoperative assessment and perioperative cautious monitoring are necessary for successful anesthesia management. [Archives Medical Review Journal 2016; 25(2.000: 140-151

    Nowadays the automotive industry makes a quantum shift to a future, where the driver will have smaller and smaller role in driving his or her vehicle ending up being totally excluded. In this paper, we have investigated the different levels of driving automatization, the prospective effects of these new technologies on the environment and traffic safety, the importance of regulations and their current state, the moral aspects of introducing these technologies and the possible scenarios of deploying the autonomous vehicles. We have found that the self-driving technologies are facing many challenges: a) They must make decisions faster in very diverse conditions which can include many moral dilemmas as well; b) They have an important potential in reducing the environmental pollution by optimizing their routes, driving styles by communicating with other vehicles, infrastructures and their environment; c) There is a considerable gap between the self-drive technology level and the current regulations; fortunately, this gap shows a continuously decreasing trend; d) In case of many types of imminent accidents management there are many concerns about the ability of making the right decision. Considering that this field has an extraordinary speed of development, our study is up to date at the submission deadline. Self-driving technologies become increasingly sophisticated and technically accessible, and in some cases, they can be deployed for commercial vehicles as well. According to the current stage of research and development, it is still unclear how the self-driving technologies will be able to handle extreme and unexpected events including their moral aspects. Since most of the traffic accidents are caused by human error or omission, it is expected that the emergence of the autonomous technologies will reduce these accidents in their number and gravity, but the very few currently available test results have not been able to scientifically underpin this issue yet.

    (Ponencia presentada en el Foro Nacional del Consejo Superior de Instituciones Médicas, Cartagena, Abril 3, 1995.

    Cuandoquiera que, en foros recientes, hemos tratado de plantear este candente tema, la primera pregunta que surge, casi al unísono, es: ¿Cuál autonomía? Porque, sin tratar de ser irónicos ni insidiosos, se aprecia que en esta finalización del siglo XX ese concepto de autonomía, que pareció florecer desde Hipócrates y mantenerse durante más de 2.000 años, parece venir languideciendo gracias a las innumerables restricciones, éticas, sociales, informáticas, gubernamentales, tecnológicas y gremiales al ejercicio de la profesión, lo mismo que a la injerencia cada vez mayor de las corporaciones económicas del mundo en las decisiones que se toman con respecto a la salud de los individuos o de las comunidades.

    De entrada, al analizar el tema, debemos definir qué es autonomía. Aunque todos la entendemos comouna especie de facultad omnímoda de hacer lo que queramos, sin restricción alguna, lo que en lenguaje jurídico se conoce como “autodeterminación”, a la luz de la ética médica se define como la capacidad de comprender la situación propia y de perseguir objetivos personales sin estar dominado por coacciones. Ese principio, sostienen Beauchamp y McCullough O, alude a que se tiene soberanía sobre la propia vida; una soberanía que protege la intimidad y también los derechos de controlar lo que suceda a cada persona y a sus bienes. En otras palabras, la soberanía de una persona limita la esfera en que los demás pueden legítimamente entrometerse. Y, como corolario, los derechos de soberanía individual protegen la libertad del individuo para elegir sus mejores intereses.

    Los eticistas, sin embargo, insisten mucho en que a la autonomía del médico debe equipararse, también, la autonomía del paciente. En el acto médico, dicen ellos, se trata de dos partes en que

    PURPOSE OF REVIEW: Sleep and cluster headache (CH) are believed to be interconnected but the precise relation to the other trigeminal autonomic cephalalgias (TACs) is uncertain and complex. A better understanding of these relations may eventually lead to a clarification of the underlying mechanisms...... and eventually to more effective therapeutic regimens. This review aims to evaluate the existing literature on the subject of TACs and sleep. An association between episodic CH and distinct macrostructural sleep phases, especially the relation to rapid eye movement (REM) sleep, has been described in some older...... studies but could not be confirmed in other, more recent studies. Investigations into the microstructure of sleep in these patients are lacking. Only a few case reports exist on the relation between sleep and other TACs.

    The goal of Autonomous Medical Care (AMC) is to ensure a healthy, well-performing crew which is a primary need for exploration. The end result of this effort will be the requirements and design for medical systems for the CEV, lunar operations, and Martian operations as well as a ground-based crew health optimization plan. Without such systems, we increase the risk of medical events occurring during a mission and we risk being unable to deal with contingencies of illness and injury, potentially threatening mission success. AMC has two major components: 1) pre-flight crew health optimization and 2) in-flight medical care. The goal of pre-flight crew health optimization is to reduce the risk of illness occurring during a mission by primary prevention and prophylactic measures. In-flight autonomous medical care is the capability to provide medical care during a mission with little or no real-time support from Earth. Crew medical officers or other crew members provide routine medical care as well as medical care to ill or injured crew members using resources available in their location. Ground support becomes telemedical consultation on-board systems/people collect relevant data for ground support to review. The AMC system provides capabilities to incorporate new procedures and training and advice as required. The on-board resources in an autonomous system should be as intelligent and integrated as is feasible, but autonomous does not mean that no human will be involved. The medical field is changing rapidly, and so a challenge is to determine which items to pursue now, which to leverage other efforts (e.g. military), and which to wait for commercial forces to mature. Given that what is used for the CEV or the Moon will likely be updated before going to Mars, a critical piece of the system design will be an architecture that provides for easy incorporation of new technologies into the system. Another challenge is to determine the level of care to provide for each

    This is an era of rapid change from ancient human-mediated modes of astronomical practice to a vision of ever larger time domain surveys, ever bigger "big data", to increasing numbers of robotic telescopes and astronomical automation on every mountaintop. Over the past decades, facets of a new autonomous astronomical toolkit have been prototyped and deployed in support of numerous space missions. Remote and queue observing modes have gained significant market share on the ground. Archives and data-mining are becoming ubiquitous; astroinformatic techniques and virtual observatory standards and protocols are areas of active development. Astronomers and engineers, planetary and solar scientists, and researchers from communities as diverse as particle physics and exobiology are collaborating on a vast range of "multi-messenger" science.

    2016-10-01

    Most surveillance systems combine camera sensors with other detection sensors that trigger an alert to a human operator when an object is detected. The detection sensors typically require careful installation and configuration for each application and there is a significant burden on the operator to react to each alert by viewing camera video feeds. A demonstration system known as Sensing for Asset Protection with Integrated Electronic Networked Technology (SAPIENT) has been developed to address these issues using Autonomous Sensor Modules (ASM) and a central High Level Decision Making Module (HLDMM) that can fuse the detections from multiple sensors. This paper describes the 24 GHz radar based ASM, which provides an all-weather, low power and license exempt solution to the problem of wide area surveillance. The radar module autonomously configures itself in response to tasks provided by the HLDMM, steering the transmit beam and setting range resolution and power levels for optimum performance. The results show the detection and classification performance for pedestrians and vehicles in an area of interest, which can be modified by the HLDMM without physical adjustment. The module uses range-Doppler processing for reliable detection of moving objects and combines Radar Cross Section and micro-Doppler characteristics for object classification. Objects are classified as pedestrian or vehicle, with vehicle sub classes based on size. Detections are reported only if the object is detected in a task coverage area and it is classified as an object of interest. The system was shown in a perimeter protection scenario using multiple radar ASMs, laser scanners, thermal cameras and visible band cameras. This combination of sensors enabled the HLDMM to generate reliable alerts with improved discrimination of objects and behaviours of interest.

    In the last decade, a variety of robotic/intelligent wheelchairs have been proposed to meet the need in aging society. Their main research topics are autonomous functions such as moving toward some goals while avoiding obstacles, or user-friendly interfaces. Although it is desirable for wheelchair users to go out alone, caregivers often accompany them. Therefore we have to consider not only autonomous functions and user interfaces but also how to reduce caregivers' load and support their activities in a communication aspect. From this point of view, we have proposed a robotic wheelchair moving with a caregiver side by side based on the MATLAB process. In this project we discussing about robotic wheel chair to follow a caregiver by using a microcontroller, Ultrasonic sensor, keypad, Motor drivers to operate robot. Using camera interfaced with the DM6437 (Davinci Code Processor) image is captured. The captured image are then processed by using image processing technique, the processed image are then converted into voltage levels through MAX 232 level converter and given it to the microcontroller unit serially and ultrasonic sensor to detect the obstacle in front of robot. In this robot we have mode selection switch Automatic and Manual control of robot, we use ultrasonic sensor in automatic mode to find obstacle, in Manual mode to use the keypad to operate wheel chair. In the microcontroller unit, c language coding is predefined, according to this coding the robot which connected to it was controlled. Robot which has several motors is activated by using the motor drivers. Motor drivers are nothing but a switch which ON/OFF the motor according to the control given by the microcontroller unit.

  10. Current challenges in autonomous vehicle development

    Science.gov (United States)

    Connelly, J.; Hong, W. S.; Mahoney, R. B., Jr.; Sparrow, D. A.

    2006-05-01

    The field of autonomous vehicles is a rapidly growing one, with significant interest from both government and industry sectors. Autonomous vehicles represent the intersection of artificial intelligence (AI) and robotics, combining decision-making with real-time control. Autonomous vehicles are desired for use in search and rescue, urban reconnaissance, mine detonation, supply convoys, and more. The general adage is to use robots for anything dull, dirty, dangerous or dumb. While a great deal of research has been done on autonomous systems, there are only a handful of fielded examples incorporating machine autonomy beyond the level of teleoperation, especially in outdoor/complex environments. In an attempt to assess and understand the current state of the art in autonomous vehicle development, a few areas where unsolved problems remain became clear. This paper outlines those areas and provides suggestions for the focus of science and technology research. The first step in evaluating the current state of autonomous vehicle development was to develop a definition of autonomy. A number of autonomy level classification systems were reviewed. The resulting working definitions and classification schemes used by the authors are summarized in the opening sections of the paper. The remainder of the report discusses current approaches and challenges in decision-making and real-time control for autonomous vehicles. Suggested research focus areas for near-, mid-, and long-term development are also presented.

Estas comunidades, no conocían la propuesta pacifista de Gandhi, Matin Luther King o Mandela, y sin embargo, desde sus necesidades y procesos propios, han generado, apropiado y jalonado, en forma perfectible, iniciativas de paz desde la base, en las que la paz ha sido concebida como defensa de la vida, resistencia civil al conflicto armado, protección de la autonomía y autodeterminación de las comunidades frente a los actores armados, participación política, desarrollo desde las bases, profundización de la democracia y defensa de la cultura, entre otras. En igual forma, estas comunidades han demostrado que Colombia también es escenario de paz y que esta no sólo se construye desde el Estado y los actores armados, sino desde las bases, que se organizan sin recurrir a las armas, en escenarios locales, para darle significados propios.

  16. Development of a Commercially Viable, Modular Autonomous Robotic Systems for Converting any Vehicle to Autonomous Control

    Science.gov (United States)

    Parish, David W.; Grabbe, Robert D.; Marzwell, Neville I.

    1994-01-01

    A Modular Autonomous Robotic System (MARS), consisting of a modular autonomous vehicle control system that can be retrofit on to any vehicle to convert it to autonomous control and support a modular payload for multiple applications is being developed. The MARS design is scalable, reconfigurable, and cost effective due to the use of modern open system architecture design methodologies, including serial control bus technology to simplify system wiring and enhance scalability. The design is augmented with modular, object oriented (C++) software implementing a hierarchy of five levels of control including teleoperated, continuous guidepath following, periodic guidepath following, absolute position autonomous navigation, and relative position autonomous navigation. The present effort is focused on producing a system that is commercially viable for routine autonomous patrolling of known, semistructured environments, like environmental monitoring of chemical and petroleum refineries, exterior physical security and surveillance, perimeter patrolling, and intrafacility transport applications.

    Autonomous control systems provides the ability of self-governance beyond the conventional control system. As the complexity of mechanical and electrical systems increases, there develops a natural drive for developing robust control systems to manage complicated operations. By closing the bridge between conventional automated systems to knowledge based self-awareness systems, nominal control of operations can evolve into relying on safe critical mitigation processes to support any off-nominal behavior. Current research and development efforts lead by the Autonomous Propellant Loading (APL) group at NASA Kennedy Space Center aims to improve cryogenic propellant transfer operations by developing an automated control and health monitoring system. As an integrated systems, the center aims to produce an Autonomous Operations System (AOS) capable of integrating health management operations with automated control to produce a fully autonomous system.

    2015-12-02

    There is a large amount of research currently being done on autonomous micro-aerial vehicles (MAV), such as quadrotor helicopters or quadcopters. The ability to create a working autonomous MAV depends mainly on integrating a simultaneous localization and mapping (SLAM) solution with the rest of the system. This paper provides an introduction for creating an autonomous MAV for enclosed environments, aimed at students and professionals alike. The standard autonomous system and MAV automation are discussed, while we focus on the core concepts of SLAM systems and trajectory planning algorithms. The advantages and disadvantages of using remote processing are evaluated, and recommendations are made regarding the viability of on-board processing. Recommendations are made regarding best practices to serve as a guideline for aspirant MAV designers.

An increasing number of studies have demonstrated that acupuncture can control autonomic nerve system (ANS functions including blood pressure, pupil size, skin conductance, skin temperature, muscle sympathetic nerve activities, heart rate and/or pulse rate, and heart rate variability. Emerging evidence indicates that acupuncture treatment not only activates distinct brain regions in different kinds of diseases caused by imbalance between the sympathetic and parasympathetic activities, but also modulates adaptive neurotransmitter in related brain regions to alleviate autonomic response. This review focused on the central mechanism of acupuncture in modulating various autonomic responses, which might provide neurobiological foundations for acupuncture effects.

La autonomía de enfermería ha sido identificada como una variable importante que afecta la percepci ón de la enfermera en relación con su satisfacción en el trabajo, los ambientes positivos de su práctica profesional y la calidad del cuidado de enfermería. La suposición de que un aspecto clave de la autonom ía de enfermería es actuar con un juicio y práctica independiente, fue cuestionada en un estudio interpretativo que exploró la forma como las enfermeras entienden la autonomía en su práctica clínica y en su trabajo. Este artículo describe el proyecto de investigación, y explora el énfasis que hacen las enfermeras sobre los aspectos inherentes al ejercicio de la autonomía en su trabajo clínico. Las descripciones de sus relaciones con los médicos, colegas y directores de enfermería, ofrecen muchos ejemplos en los cuales la práctica autó- noma puede ser respaldada y fortalecida. Este artículo también discute estas posibilidades para que este concepto se pueda llevar a cabo en tres áreas claves: crear ambientes de práctica que enriquezcan la pericia clínica y la toma de decisiones; hacer posible que las enfermeras practiquen, aplicando todas sus capacidades educativas, sus experiencias y competencias; y fortalecer la práctica multidisciplinaria con colaboración.

    The primary objective this summer is "evaluating standards for wireless architecture for the internet of things". The Internet of Things is the network of physical objects or "things" embedded with electronics, software, sensors and network connectivity which enables these objects to collect and exchange data and make decisions based on said data. This was accomplished by creating a semi-autonomous vehicle that takes advantage of multiple sensors, cameras, and onboard computers and combined them with a mesh network which enabled communication across large distances with little to no interruption. The mesh network took advantage of what is known as DTN - Disruption Tolerant Networking which according to NASA is the new communications protocol that is "the first step towards interplanetary internet." The use of DTN comes from the fact that it will store information if an interruption in communications is detected and even forward that information via other relays within range so that the data is not lost. This translates well into the project because as the car moves further away from whatever is sending it commands (in this case a joystick), the information can still be forwarded to the car with little to no loss of information thanks to the mesh nodes around the driving area.

    Full Text Available The autonomous ship technology has become a “hot” topic in the discussion about more efficient, environmentally friendly and safer sea transportation solutions. The time is becoming mature for the introduction of commercially sensible solutions for unmanned and fully autonomous cargo and passenger ships. Safety will be the most interesting and important aspect in this development. The utilization of the autonomous ship technology will have many effects on the safety, both positive and negative. It has been announced that the goal is to make the safety of an unmanned ship better that the safety of a manned ship. However, it must be understood that the human element will still be present when fully unmanned ships are being used. The shore-based control of a ship contains new safety aspects and an interesting question will be the interaction of manned and unmanned ships in the same traffic area. The autonomous ship technology should therefore be taken into account on the training of seafarers. Also it should not be forgotten that every single control algorithm and rule of the internal decision making logic of the autonomously navigating ship has been designed and coded by a human software engineer. Thus the human element is present also in this point of the lifetime navigation system of the autonomous ship.

    2014-01-01

    Starting in Jan 2012, the Advanced Exploration Systems (AES) Autonomous Mission Operations (AMO) Project began to investigate the ability to create and execute "single button" crew initiated autonomous activities [1]. NASA Marshall Space Flight Center (MSFC) designed and built a fluid transfer hardware test-bed to use as a sub-system target for the investigations of intelligent procedures that would command and control a fluid transfer test-bed, would perform self-monitoring during fluid transfers, detect anomalies and faults, isolate the fault and recover the procedures function that was being executed, all without operator intervention. In addition to the development of intelligent procedures, the team is also exploring various methods for autonomous activity execution where a planned timeline of activities are executed autonomously and also the initial analysis of crew procedure development. This paper will detail the development of intelligent procedures for the NASA MSFC Autonomous Fluid Transfer System (AFTS) as well as the autonomous plan execution capabilities being investigated. Manned deep space missions, with extreme communication delays with Earth based assets, presents significant challenges for what the on-board procedure content will encompass as well as the planned execution of the procedures.

  5. Autonomous power networks based power system

    International Nuclear Information System (INIS)

    Jokic, A.; Van den Bosch, P.P.J.

    2006-01-01

    This paper presented the concept of autonomous networks to cope with this increased complexity in power systems while enhancing market-based operation. The operation of future power systems will be more challenging and demanding than present systems because of increased uncertainties, less inertia in the system, replacement of centralized coordinating activities by decentralized parties and the reliance on dynamic markets for both power balancing and system reliability. An autonomous network includes the aggregation of networked producers and consumers in a relatively small area with respect to the overall system. The operation of an autonomous network is coordinated and controlled with one central unit acting as an interface between internal producers/consumers and the rest of the power system. In this study, the power balance problem and system reliability through provision of ancillary services was formulated as an optimization problem for the overall autonomous networks based power system. This paper described the simulation of an optimal autonomous network dispatching in day ahead markets, based on predicted spot prices for real power, and two ancillary services. It was concluded that large changes occur in a power systems structure and operation, most of them adding to the uncertainty and complexity of the system. The introduced concept of an autonomous power network-based power system was shown to be a realistic and consistent approach to formulate and operate a market-based dispatch of both power and ancillary services. 9 refs., 4 figs

  6. The role of autonomic testing in syncope.

    Science.gov (United States)

    Jones, Pearl K; Gibbons, Christopher H

    2014-09-01

    Syncope is a common presenting complaint in both the inpatient and outpatient settings. The main goals in the clinical evaluation of syncope are to identify an underlying etiology, to stratify risk and to guide plans for therapeutic intervention. Testing begins with an initial electrocardiogram to screen for any cardiac rhythm abnormalities. Heart rate variability to paced breathing provides a standard measure of cardiac parasympathetic function and offers clues towards an autonomic cause of syncope. A Valsalva maneuver is used to evaluate for parasympathetic dysfunction through the Valsalva ratio. In addition, sympathetic adrenergic function is assessed through evaluation of blood pressure response during the Valsalva maneuver. Abnormalities to the Valsalva maneuver can suggest clues towards an autonomic cause of syncope. Head-up tilt table testing is an important part of the autonomic evaluation of patients with syncope, and can be diagnostic for many disorders that result in syncope including orthostatic hypotension, neurally mediated syncope, postural tachycardia syndrome or delayed orthostatic hypotension. Autonomic function testing provides a safe and controlled environment for evaluation of patients, and plays a pivotal role in the diagnosis of syncope, particularly in challenging cases. While the initial clinical evaluation of syncope involves a detailed history and physical examination; in situations where the diagnosis is unknown, the addition of autonomic testing is complementary and can lead to identification of autonomic causes of syncope.

  7. Cardiac autonomic dysfunction in West syndrome.

    Jansen, Katrien; Vandeput, Steven; Van Huffel, Sabine; Lagae, Lieven

    2012-12-01

    West syndrome is an age-dependent epileptic encephalopathy. Autonomic changes are increasingly being recognized in patients with epilepsy: cardiac autonomic function is mediated by sympathetic and parasympathetic efferent activity to the heart and can provide information on the functional state of the autonomic nervous system. The goal of the study is to evaluate the effect of an early epileptic encephalopathy on the autonomic nervous system by measuring heart rate variability. Cardiac autonomic function was evaluated in 13 patients with West syndrome by measuring heart rate variability during 5 min epochs of ECG in wake, stage 2 and slow wave sleep. In 5 patients who developed subsequently another type of epilepsy, a second evaluation was performed after 3 years of follow-up. Results showed a lower heart rate in stage 2 sleep in patients with West syndrome. Spectral components did not show significant differences compared to age matched controls at the moment of presentation. After follow-up of 3 years we were able to demonstrate higher low frequency (LF), lower high frequency (HF) and a higher LF/HF ratio during slow wave sleep. This study shows a lower heart rate in patients presenting with West syndrome, already at the onset of the syndrome and before ACTH treatment. The epileptic encephalopathy is not sufficient to alter spectral components of heart rate at the moment of presentation. However, already after 3 years of epilepsy, chronic autonomic changes appear.

    Full Text Available Resumen: Distintas prácticas políticas de educación de los pueblos indígenas de Las Cañadas de Ocosingo, en Chiapas, están analizadas aquí a partir de un enfoque sociológico. La experiencia zapatista de autonomía aporta una demostración del cuestionamiento profundo de la política de educación del Estado nación. Los proyectos de educación de los pueblos indígenas que pertenecen a los municipios zapatistas desafían las prácticas institucionalizadas de los actores dominantes en este campo en México, y en el contexto latinoamericano de las luchas de los pueblos originarios para cambiar la normatividad de las políticas educativas. Además, la experiencia zapatista en la región de las tierras recuperadas de la Selva Lacandona pone en tela de juicio las limitaciones del proyecto nacional heredado de teorías y prácticas del indigenismo mexicano que hoy están inmersas en los discursos del multiculturalismo neoliberal, en los cuales se elude la cuestión social de la autonomía política.

    Full Text Available La capacitación para el trabajo constituye una herramienta importante para las mujeres, ya que les permite estar en mejores condiciones para ingresar o mantenerse en el mundo laboral; sin embargo, ellas viven diversas tensiones al tratar de compaginar la vida familiar con la capacitación. Este texto es resultado de una investigación cualitativa basada en el método biográfico, diseñada para analizar el significado que tiene dicha capacitación en la vida personal, familiar y laboral de las mujeres. Entre los resultados se encontró, que el incremento en su formación no ha modificado sustancialmente la visión tradicional sobre las funciones sociales de las mujeres y los hombres, pero las ayuda a impulsar su autonomía personal y económica, sin renunciar a sus responsabiliades reproductivas y familiares. Las mujeres asignan valor tanto al ámbito doméstico como al público, y los consideran como espacios diferenciados que es necesario concertar.

  13. Autonomous Vehicles: Disengagements, Accidents and Reaction Times.

    2016-01-01

    Autonomous vehicles are being viewed with scepticism in their ability to improve safety and the driving experience. A critical issue with automated driving at this stage of its development is that it is not yet reliable and safe. When automated driving fails, or is limited, the autonomous mode disengages and the drivers are expected to resume manual driving. For this transition to occur safely, it is imperative that drivers react in an appropriate and timely manner. Recent data released from the California trials provide compelling insights into the current factors influencing disengagements of autonomous mode. Here we show that the number of accidents observed has a significantly high correlation with the autonomous miles travelled. The reaction times to take control of the vehicle in the event of a disengagement was found to have a stable distribution across different companies at 0.83 seconds on average. However, there were differences observed in reaction times based on the type of disengagements, type of roadway and autonomous miles travelled. Lack of trust caused by the exposure to automated disengagements was found to increase the likelihood to take control of the vehicle manually. Further, with increased vehicle miles travelled the reaction times were found to increase, which suggests an increased level of trust with more vehicle miles travelled. We believe that this research would provide insurers, planners, traffic management officials and engineers fundamental insights into trust and reaction times that would help them design and engineer their systems.

    2017-05-01

    The utility of micro air vehicles (MAVs) has expanded significantly in the last decade, and there are now numerous commercial systems available at relatively low cost. This expansion has arisen mainly due to the miniaturisation of flight control systems and advances in energy storage and propulsion technologies. Several emerging applications involve routine operation of MAVs in complex urban environments such as parcel delivery, communications relay and environmental monitoring. However, MAVs currently rely on one or more operators-in-the-loop and, whilst desirable, full autonomous operation has not yet been achieved. In this review paper, autonomous MAV operation in complex environments is explored with conceptualisation for future MAV operation in urban environments. Limitations of current technologies are systematically examined through consideration of the state-of-the-art and future trends. The main limitations challenging the realisation of fully autonomous MAVs are mainly attributed to: computational power, communication and energy storage. These limitations lead to poor sensing and planning capabilities, which are essential components of autonomous MAVs. Possible solutions are explored with goal of enabling MAVs to reliably operate autonomously in urban environments.

    Ringer, Mark J.; Quinn, Todd M.; Merolla, Anthony

    1992-01-01

    The Autonomous Power System (APS) project at the NASA Lewis Research Center is designed to demonstrate the applications of integrated intelligent diagnosis, control and scheduling techniques to space power distribution systems. The project consists of three elements: the Autonomous Power Expert System (APEX) for Fault Diagnosis, Isolation, and Recovery (FDIR); the Autonomous Intelligent Power Scheduler (AIPS) to efficiently assign activities start times and resources; and power hardware (Brassboard) to emulate a space-based power system. The APS project had been through one design iteration. Each of the three elements of the APS project has been designed, tested, and integrated into a complete working system. After these three portions were completed, an evaluation period was initiated. Each piece of the system was critiqued based on individual performance as well as the ability to interact with the other portions of the APS project. These critiques were then used to determine guidelines for new and improved components of the APS system.

    The Autonomous Sciencecraft Experiment (ASE), part of the New Millennium Space Technology 6 Project, is flying onboard the Earth Orbiter 1 (EO-1) mission. The ASE software enables EO-1 to autonomously detect and respond to science events such as: volcanic activity, flooding, and water freeze/thaw. ASE uses classification algorithms to analyze imagery onboard to detect chang-e and science events. Detection of these events is then used to trigger follow-up imagery. Onboard mission planning software then develops a response plan that accounts for target visibility and operations constraints. This plan is then executed using a task execution system that can deal with run-time anomalies. In this paper we describe the autonomy flight software and how it enables a new paradigm of autonomous science and mission operations. We will also describe the current experiment status and future plans.

    The On-Orbit Autonomous Assembly from Nanosatellites (OAAN) project will demonstrate autonomous control algorithms for rendezvous and docking maneuvers; low-power reconfigurable magnetic docking technology; and compact, lightweight and inexpensive precision relative navigation using carrier-phase differential (CD) GPS with a three-degree of freedom ground demonstration. CDGPS is a specific relative position determination method that measures the phase of the GPS carrier wave to yield relative position data accurate to.4 inch (1 centimeter). CDGPS is a technology commonly found in the surveying industry. The development and demonstration of these technologies will fill a current gap in the availability of proven autonomous rendezvous and docking systems for small satellites.

    Objective is to evaluate cardiovascular autonomic function in SLE by simple non-invasive tests. A case control study was carried out involving 18-50 yrs old previously diagnosed SLE patients and same number of age and sex-matched controls. Parasympathetic function was assessed by heart rate (HR) response to Valsalva maneuver, deep breathing and standing. Sympathetic function was evaluated by blood pressure response to standing and sustained hand-grip test (HGT). There were 50 female SLE patients. They had significantly higher minimum resting HR and diastolic blood pressure (DBP). HR variation with deep breathing, expiratory inspiratory ratio, 30:15 ratio and DBP change in response to HGT were significantly lower inpatients compared to controls. Thirty patients (60%) had at least one abnormal or two borderline test results indicating autonomic impairment of which 27 had parasympathetic dysfunction and 7 had sympathetic dysfunction. Autonomic dysfunction is common in SLE with higher prevalence of parasympathetic impairment.

    2016-01-01

    This book takes a look at fully automated, autonomous vehicles and discusses many open questions: How can autonomous vehicles be integrated into the current transportation system with diverse users and human drivers? Where do automated vehicles fall under current legal frameworks? What risks are associated with automation and how will society respond to these risks? How will the marketplace react to automated vehicles and what changes may be necessary for companies? Experts from Germany and the United States define key societal, engineering, and mobility issues related to the automation of vehicles. They discuss the decisions programmers of automated vehicles must make to enable vehicles to perceive their environment, interact with other road users, and choose actions that may have ethical consequences. The authors further identify expectations and concerns that will form the basis for individual and societal acceptance of autonomous driving. While the safety benefits of such vehicles are tremendous, the auth...

    A power system testbed has been assembled to advance the development of large autonomous electrical power systems required for the space station, spacecraft, and aircraft. The power system for this effort was designed to simulate single- or dual-bus autonomous power systems, or autonomous systems that reconfigure from a single bus to a dual bus following a severe fault. The approach taken was to provide a flexible power system design with two computer systems for control and management. One computer operates as the control system and performs basic control functions, data and command processing, charge control, and provides status to the second computer. The second computer contains expert system software for mission planning, load management, fault identification and recovery, and sends load and configuration commands to the control system

  5. Control of autonomous robot using neural networks

    Barton, Adam; Volna, Eva

    2017-07-01

    The aim of the article is to design a method of control of an autonomous robot using artificial neural networks. The introductory part describes control issues from the perspective of autonomous robot navigation and the current mobile robots controlled by neural networks. The core of the article is the design of the controlling neural network, and generation and filtration of the training set using ART1 (Adaptive Resonance Theory). The outcome of the practical part is an assembled Lego Mindstorms EV3 robot solving the problem of avoiding obstacles in space. To verify models of an autonomous robot behavior, a set of experiments was created as well as evaluation criteria. The speed of each motor was adjusted by the controlling neural network with respect to the situation in which the robot was found.

    Fully autonomous precise control of qubits is crucial for quantum information processing, quantum communication, and quantum sensing applications. It requires minimal human intervention on the ability to model, to predict, and to anticipate the quantum dynamics, as well as to precisely control and calibrate single qubit operations. Here, we demonstrate single qubit autonomous calibrations via closed-loop optimisations of electron spin quantum operations in diamond. The operations are examined by quantum state and process tomographic measurements at room temperature, and their performances against systematic errors are iteratively rectified by an optimal pulse engineering algorithm. We achieve an autonomous calibrated fidelity up to 1.00 on a time scale of minutes for a spin population inversion and up to 0.98 on a time scale of hours for a single qubit π/2 -rotation within the experimental error of 2%. These results manifest a full potential for versatile quantum technologies.

    With their prospect for causing both novel and known forms of damage, harm and injury, the issue of responsibility has been a recurring theme in the debate concerning autonomous vehicles. Yet, the discussion of responsibility has obscured the finer details both between the underlying concepts...... of responsibility, and their application to the interaction between human beings and artificial decision-making entities. By developing meaningful distinctions and examining their ramifications, this article contributes to this debate by refining the underlying concepts that together inform the idea...... of responsibility. Two different approaches are offered to the question of responsibility and autonomous vehicles: targeting and risk distribution. The article then introduces a thought experiment which situates autonomous vehicles within the context of crash optimisation impulses and coordinated or networked...

    Full Text Available The present study tried to determine Turkish learners’ attitudes, and the Turkish education system’s approach towards learner autonomy with regard to three main points: 1 whether Turkish university students are aware of learner autonomy or not 2 whether Turkish university students have the characteristics of autonomous learners (whether they are autonomous learners or not, and 3 if the Turkish education system is suitable for fostering learner autonomy or not from the viewpoint of the participants. Participants were 50 second grade learners in the English Language Teaching Departments of Hacettepe University (N=10, Mehmet Akif Ersoy University (N=10, and Uludag University (N=30 who had already taken courses about learner autonomy.  The data were collected by means of a questionnaire which had two Likert-scale sections and an open-ended questions section. The first Likert-scale section contained 15 characteristics of autonomous learners each of which was rated by the participants in a scale from strongly disagree to agree, from 1 to 5. In the second Likert-scale section, the participants were asked to rate the Turkish education system’s five basic elements such as school curriculums, course materials, approaches used by the teachers in classrooms, learning activities, and classroom settings. Additionally, learners’ opinions about their awareness and understanding of learner autonomy were gathered by five open ended questions. The results proposed that the participants were aware of learner autonomy, and had the characteristics of autonomous learners. On the other hand, results showed that the Turkish education system was not suitable for autonomous learners and did not foster learner autonomy. The findings suggested that the Turkish education system should be designed again in such a way to support the autonomous learners and to foster learner autonomy in all sections of the education.

    2011-11-01

    Full Text Available En sistemas marcarios, como el de la Comunidad Andina, una autoridad estatal verifica que las marcas sean distintivas, lícitas y no afecten a terceros, y, luego de ello, concede su titularidad. En este contexto, ha suscitado un especial interés la posibilidad de que, mediante acuerdos o declaraciones de coexistencia, sean los particulares los que aseguren que sus signos cumplen las condiciones para obtener registros simultáneos. Tales negocios jurídicos para la coexistencia de marcas resultan problemáticos si se piensa que los titulares estarían disponiendo de intereses que parecen importar también a los consumidores, competidores y al mercado. Por lo tanto, precisar el margen de libertad contractual en el ámbito del derecho marcario, cuyas normas son consideradas de orden público, adquiere importancia práctica y teórica, puesto que su concreción: i reconoce los riesgos cuya evaluación puede ser relevante al negociar los acuerdos y ii contribuye a los debates sobre el papel de la autonomía privada en aquellos ámbitos reservados para normas inderogables. Así, esta investigación sitúa las declaraciones de consentimiento para la coexistencia de registros en Colombia en un cuadro más amplio, el de los límites de la autonomía contractual.

    2017-03-01

    Over the course of the last decade great advances have been made in autonomously driving cars. The technology has advanced to the point that driverless car technology is currently being tested on publicly accessed roadways. The introduction of these technologies onto publicly accessed roadways not only raises questions of safety, but also security. Autonomously driving cars are inherently cyber-physical systems and as such will have novel security vulnerabilities that couple both the cyber aspects of the vehicle including the on-board computing and any network data it makes use of, with the physical nature of the vehicle including its sensors, actuators, and the vehicle chassis. Widespread implementation of driverless car technology will require that both the cyber, as well as physical security concerns surrounding these vehicles are addressed. In this work, we specifically developed a control policy to autonomously execute the Precision Immobilization Technique, a.k.a. the PIT maneuver. The PIT maneuver was originally developed by law enforcement to end high-speed vehicular pursuits in a quasi-safe manner. However, there is still a risk of damage/roll-over to both the vehicle executing the PIT maneuver as well as to the vehicle subject to the PIT maneuver. In law enforcement applications, it would be preferable to execute the PIT maneuver using an autonomous vehicle, thus removing the danger to law-enforcement officers. Furthermore, it is entirely possible that unscrupulous individuals could inject code into an autonomously-driving car to use the PIT maneuver to immobilize other vehicles while maintaining anonymity. For these reasons it is useful to know how the PIT maneuver can be implemented on an autonomous car. In this work a simple control policy based on velocity pursuit was developed to autonomously execute the PIT maneuver using only a vision and range measurements that are both commonly collected by contemporary driverless cars. The ability of this

    An advanced control architecture for autonomous vehicles is presented. The hierarchical architecture consists of four levels: a vehicle level, a control level, a rule-based level and a knowledge-based level. A special focus is on forms of internal representation, which have to be chosen adequately for each level. The control scheme is applied to VaMP, a Mercedes passenger car which autonomously performs missions on German freeways. VaMP perceives the environment with its sense of vision and conventional sensors. It controls its actuators for locomotion and attention focusing. Modules for perception, cognition and action are discussed.

De manera complementaria, fueron además dispuestas en la tarea las características que en estudios relacionados habían sido reportadas como facilitadoras de ejecuciones efectivas, a saber: el uso de instrucciones inespecíficas, arreglos de estímulo de tres formas y dos colores y el entrenamiento concurrente de las relaciones. Ocho sujetos fueron distribuidos en cuatro grupos que variaron en la combinación de relaciones a entrenar. Los resultados mostraron que gran parte de los sujetos cumplieron con el criterio de efectividad en entrenamiento y en transferencia extramodal y extrarrelacional, siendo la relación de identidad la relación en la cual se presentaron ejecuciones perfectas, al margen de si ésta había sido entrenada o no. Se discuten los resultados en términos de velocidad de ajuste a las relaciones y de las configuraciones de la tarea que facilitaron mejores desempeños. Se proponen, además, posibles investigaciones que superen las limitaciones metodológicas encontradas en este estudio y que exploren posibles interacciones de las variables manipuladas con otras variables de interés.

    2017-08-01

    Full Text Available Several Generation IV nuclear reactor concepts have goals for optimizing investment recovery through phased introduction of multiple units on a common site with shared facilities and/or reconfigurable energy conversion systems. Additionally, small modular reactors are suitable for remote deployment to support highly localized microgrids in isolated, underdeveloped regions. The long-term economic viability of these advanced reactor plants depends on significant reductions in plant operations and maintenance costs. To accomplish these goals, intelligent control and diagnostic capabilities are needed to provide nearly autonomous operations with anticipatory maintenance. A nearly autonomous control system should enable automatic operation of a nuclear power plant while adapting to equipment faults and other upsets. It needs to have many intelligent capabilities, such as diagnosis, simulation, analysis, planning, reconfigurability, self-validation, and decision. These capabilities have been the subject of research for many years, but an autonomous control system for nuclear power generation remains as-yet an unrealized goal. This article describes a functional framework for intelligent, autonomous control that can facilitate the integration of control, diagnostic, and decision-making capabilities to satisfy the operational and performance goals of power plants based on multimodular advanced reactors.

  19. The CASCADAS Framework for Autonomic Communications

    Science.gov (United States)

    Baresi, Luciano; Ferdinando, Antonio Di; Manzalini, Antonio; Zambonelli, Franco

    An interesting approach to the design and development of the future Internet foresees a networked service eco-system capable of seamlessly offering services for human-to-human, human-to-machine and machine-to-machine interactions. This chapter builds in this direction by describing a distributed component-ware framework for autonomic and situation-aware communication developed within the CASCADAS project. The core of this framework is the Autonomic Communication Element (ACE), an innovative software abstraction capable of providing dynamically adaptable services that can be built, composed, and let evolve according to autonomic principles. Services are capable of adapting their logic to the dynamically changing context they operate in without human intervention. As a result, whenever the need arises, ACEs can be federated autonomously and produce new services on a situation-aware basis. Systems and, in particular, eco-systems can thus be conceived as collections of ACEs. The chapter introduces the concept of ACE and its different facets. It also presents the architecture of a prototype ACE-based platform and exemplifies the different concepts through a future Pervasive Behavioral Advertisement scenario.

    The idea of building autonomous robots that can carry out complex and nonrepetitive tasks is an old one, so far unrealized in any meaningful hardware. Tilden has shown recently that there are simple, processor-free solutions to building autonomous mobile machines that continuously adapt to unknown and hostile environments, are designed primarily to survive, and are extremely resistant to damage. These devices use smart mechanics and simple (low component count) electronic neuron control structures having the functionality of biological organisms from simple invertebrates to sophisticated members of the insect and crab family. These devices are paradigms for the development of autonomous machines that can carry out directed goals. The machine then becomes a robust survivalist platform that can carry sensors or instruments. These autonomous roving machines, now in an early stage of development (several proof-of-concept prototype walkers have been built), can be developed so that they are inexpensive, robust, and versatile carriers for a variety of instrument packages. Applications are immediate and many, in areas as diverse as prosthetics, medicine, space, construction, nanoscience, defense, remote sensing, environmental cleanup, and biotechnology

    2012-06-01

    Diabetic cardiovascular autonomic neuropathy (DCAN), the impairment of the autonomic balance of the cardiovascular system in the setting of diabetes mellitus (DM), is frequently observed in both Type 1 and 2 DM, has detrimental effects on the quality of life and portends increased mortality. Clinical manifestations include: resting heart rate disorders, exercise intolerance, intraoperative cardiovascular lability, orthostatic alterations in heart rate and blood pressure, QT-interval prolongation, abnormal diurnal and nocturnal blood pressure variation, silent myocardial ischemia and diabetic cardiomyopathy. Clinical tests for autonomic nervous system evaluation, heart rate variability analysis, autonomic innervation imaging techniques, microneurography and baroreflex analysis are the main diagnostic tools for DCAN detection. Aldose reductase inhibitors and antioxidants may be helpful in DCAN therapy, but a regular, more generalized and multifactorial approach should be adopted with inclusion of lifestyle modifications, strict glycemic control and treatment of concomitant traditional cardiovascular risk factors, in order to achieve the best therapeutic results. In the present review, the authors provide aspects of DCAN pathophysiology, clinical presentation, diagnosis and an algorithm regarding the evaluation and management of DCAN in DM patients.

  1. A Multifunctional Coating for Autonomous Corrosion Control

    Science.gov (United States)

    Calle, Luz M.; Li, Wenyan; Buhrow, Jerry W.; Jolley, Scott t.

    2011-01-01

    Nearly all metals and their alloys are subject to corrosion that causes them to lose their structural integrity or other critical functionality. Protective coatings are the most commonly used method of corrosion control. However, progressively stricter environmental regulations have resulted in the ban of many commercially available corrosion protective coatings due to the harmful effects of their solvents or corrosion inhibitors. This work concerns the development of a multifunctional smart coating for the autonomous control of corrosion. This coating is being developed to have the inherent ability to detect the chemical changes associated with the onset of corrosion and respond autonomously to indicate it and control it. The multi-functionality of the coating is based on microencapsulation technology specifically designed for corrosion control applications. This design has, in addition to all the advantages of existing microcapsulation designs, the corrosion controlled release function that triggers the delivery of corrosion indicators and inhibitors on demand, only when and where needed. Microencapsulation of self-healing agents for autonomous repair of mechanical damage to the coating is also being pursued. Corrosion indicators, corrosion inhibitors, as well as self-healing agents, have been encapsulated and dispersed into several paint systems to test the corrosion detection, inhibition, and self-healing properties of the coating. Key words: Corrosion, coating, autonomous corrosion control, corrosion indication, corrosion inhibition, self-healing coating, smart coating, multifunctional coating, microencapsulation.

    New missions of exploration and space operations will require unprecedented levels of autonomy to successfully accomplish their objectives. Inherently high levels of complexity, cost, and communication distances will preclude the degree of human involvement common to current and previous space flight missions. With exponentially increasing capabilities of computer hardware and software, including networks and communication systems, a new balance of work is being developed between humans and machines. This new balance holds the promise of not only meeting the greatly increased space exploration requirements, but simultaneously dramatically reducing the design, development, test, and operating costs. New information technologies, which take advantage of knowledge-based software, model-based reasoning, and high performance computer systems, will enable the development of a new generation of design and development tools, schedulers, and vehicle and system health management capabilities. Such tools will provide a degree of machine intelligence and associated autonomy that has previously been unavailable. These capabilities are critical to the future of advanced space operations, since the science and operational requirements specified by such missions, as well as the budgetary constraints will limit the current practice of monitoring and controlling missions by a standing army of ground-based controllers. System autonomy capabilities have made great strides in recent years, for both ground and space flight applications. Autonomous systems have flown on advanced spacecraft, providing new levels of spacecraft capability and mission safety. Such on-board systems operate by utilizing model-based reasoning that provides the capability to work from high-level mission goals, while deriving the detailed system commands internally, rather than having to have such commands transmitted from Earth. This enables missions of such complexity and communication` distances as are not

  11. Exercise and the autonomic nervous system.

    Science.gov (United States)

    Fu, Qi; Levine, Benjamin D

    2013-01-01

    The autonomic nervous system plays a crucial role in the cardiovascular response to acute (dynamic) exercise in animals and humans. During exercise, oxygen uptake is a function of the triple-product of heart rate and stroke volume (i.e., cardiac output) and arterial-mixed venous oxygen difference (the Fick principle). The degree to which each of the variables can increase determines maximal oxygen uptake (V˙O2max). Both "central command" and "the exercise pressor reflex" are important in determining the cardiovascular response and the resetting of the arterial baroreflex during exercise to precisely match systemic oxygen delivery with metabolic demand. In general, patients with autonomic disorders have low levels of V˙O2max, indicating reduced physical fitness and exercise capacity. Moreover, the vast majority of the patients have blunted or abnormal cardiovascular response to exercise, especially during maximal exercise. There is now convincing evidence that some of the protective and therapeutic effects of chronic exercise training are related to the impact on the autonomic nervous system. Additionally, training induced improvement in vascular function, blood volume expansion, cardiac remodeling, insulin resistance and renal-adrenal function may also contribute to the protection and treatment of cardiovascular, metabolic and autonomic disorders. Exercise training also improves mental health, helps to prevent depression, and promotes or maintains positive self-esteem. Moderate-intensity exercise at least 30 minutes per day and at least 5 days per week is recommended for the vast majority of people. Supervised exercise training is preferable to maximize function capacity, and may be particularly important for patients with autonomic disorders. © 2013 Elsevier B.V. All rights reserved.

    This paper is to present a robust controller design method for developing autonomous landing systems of Unmanned Combat Air Vehicle (UCAV). We first analyze the characteristic of autonomous landing of UCAV, and put forward its landing performance specifications. Structure singular value μ| synthesis is used to develop autonomous landing systems to accurately follow the pre-designed ideal landing track or online generated optimal landing track. The robust performance of system is analyzed. The simulation results demonstrate that the designed autonomous landing system satisfies the performance requirements of autonomous landing of UCAV when there are uncertainties of UCAV aircraft model, measurement noises and exogenous disturbances.

    Autonomic Computing (AC), a self-managing systems initiative based on the biological metaphor of the autonomic nervous system, is increasingly gaining momentum as the way forward in designing reliable systems. Agent technologies have been identified as a key enabler for engineering autonomicity in systems, both in terms of retrofitting autonomicity into legacy systems and designing new systems. The AC initiative provides an opportunity to consider other biological systems and principles in seeking new design strategies. This paper reports on one such investigation; utilizing the apoptosis metaphor of biological systems to provide a dynamic health indicator signal between autonomic agents.

    The appearance of modem global positioning systems motivated the study and development of precise and robust systems for autonomous orbit determination of artificial satellites. These systems maintain, independently from human intervention from the ground, a precise knowledge of the satellite orbital state, through the processing of the information, autonomously generated on-board, by a receiver of the positioning system used. One of the major motivations for the research and development of autonomous navigators, is the availability of real time information about the position and velocity of the satellite, required, for instance, in earth observation missions, for interpretation and analysis of the generated images. The appearance of global positioning systems and the consequent development of autonomous navigators, by making available onboard space vehicles, updated orbit estimations, with good accuracy level, made feasible the research and development of orbit autonomous control procedures. It allowed the orbital maneuvers execution process to be performed in a way totally independent from ground human intervention. Whereas the satellite attitude control reached a high level of autonomy, due to the fact that the attitude measurements are, in general, naturally generated on-board the spacecraft, the orbit control is still now almost totally planned and executed from ground commanded actions. The proposed work consists of the study, development, simulation and analysis of a simplified navigator coupled to an autonomous orbit control system, applied to the China-Brazil Earth Resources Satellites (CBERS). At first, an autonomous orbit determination procedure is developed and analyzed. Its objective is to improve the coarse geometric solution provided by Global Positioning System (GPS) receivers. This will be done by directly using this solution as input (observation) for a real time Kalman filtering process. The orbital state vector will be extended in order to

    Full Text Available Dynamic robustness and stability control is a requirement for self-driving of autonomous vehicle. Longitudinal control technique of autonomous vehicle is basic theory and one key complex technique which must have the reliability and precision of vehicle controller. The longitudinal control technique is one of the foundations of the safety and stability of autonomous vehicle control. In our paper, we present a longitudinal control algorithm based on cloud model for Mengshi autonomous vehicle to ensure the dynamic stability and tracking performance of Mengshi autonomous vehicle. The longitudinal control algorithm mainly uses cloud model generator to control the acceleration of the autonomous vehicle to achieve the goal that controls the speed of Mengshi autonomous vehicle. The proposed longitudinal control algorithm based on cloud model is verified by real experiments on Highway driving scene. The experiments results of the acceleration and speed show that the algorithm is validity and stability.

    Multiple system atrophy (MSA) can clinically be divided into the cerebellar (MSA-C) and the parkinsonian (MSA-P) variant. However, till now, it is unknown whether autonomic dysfunction in these two entities differs regarding severity and profile. We compared the pattern of autonomic dysfunction in 12 patients with MSA-C and 26 with MSA-P in comparison with 27 age- and sex-matched healthy controls using a standard battery of autonomic function tests and a structured anamnesis of the autonomic nervous system. MSA-P patients complained significantly more often about the symptoms of autonomic dysfunctions than MSA-C patients, especially regarding vasomotor, secretomotor, and gastrointestinal subsystems. However, regarding cardiovascular, sudomotor pupil, urogenital, and sleep subsystems, there were no significant quantitative or qualitative differences as analyzed by autonomic anamnesis and testing. Our results suggest that there are only minor differences in the pattern of autonomic dysfunction between the two clinical MSA phenotypes. (c) 2007 Movement Disorder Society.

    Full Text Available Este artículo examina el rápido crecimiento de las comunidades irregulares que son habitadas por población de escasos recursos, predominantemente hispana, localizadas en áreas desincorporadas de lado norteamericano de la frontera México-Estados Unidos durante la década de los ochenta. Alrededor de 175 o 200 mil personas actualmente viven en estas llamadas "colonias", mismas que frecuentemente están aisladas de las áreas urbanas cercanas y sin disponer de acceso adecuado a los servicios públicos básicos tales como agua, drenaje y transporte público. La inmigración de mexicanos a los Estados Unidos y la escasez de viviendas a precios módicos están identificados como los factores principales en la creación de estas comunidades. El Paso, Texas es utilizado como caso para el estudio de la dinámica social, política y económica del crecimiento de las "colonias". En este artículo se llega a la conclusión de que serán necesarias inciativas innovadoras, principalmente locales, para minimizar las consecuencias potenciales negativas del desarrollo irregular de anillos de pobreza alrededor de las áreas urbanas ubicadas en el lado norteamericano de la frontera.

    Rivera-Durón, R. R.; Campos-Cantón, E.; Campos-Cantón, I.; Gauthier, Daniel J.

    2015-01-01

    We present the design of an autonomous time-delay Boolean network realized with readily available electronic components. Through simulations and experiments that account for the detailed nonlinear response of each circuit element, we demonstrate that a network with five Boolean nodes displays complex behavior. Furthermore, we show that the dynamics of two identical networks display near-instantaneous synchronization to a periodic state when forced by a common periodic Boolean signal. A theoretical analysis of the network reveals the conditions under which complex behavior is expected in an individual network and the occurrence of synchronization in the forced networks. This research will enable future experiments on autonomous time-delay networks using readily available electronic components with dynamics on a slow enough time-scale so that inexpensive data collection systems can faithfully record the dynamics

    2012-01-01

    Within the DIRAC framework in the LHCb collaboration, we deployed an autonomous policy system acting as a central status information point for grid elements. Experts working as grid administrators have a broad and very deep knowledge about the underlying system which makes them very precious. We have attempted to formalize this knowledge in an autonomous system able to aggregate information, draw conclusions, validate them, and take actions accordingly. The DIRAC Resource Status System (RSS) is a monitoring and generic policy system that enforces managerial and operational actions automatically. As an example, the status of a grid entity can be evaluated using a number of policies, each making assessments relative to specific monitoring information. Individual results of these policies can be combined to evaluate and propose a global status for the resource. This evaluation goes through a validation step driven by a state machine and an external validation system. Once validated, actions can be triggered acco...

    1991-01-01

    Fuzzy logic can be used advantageously in autonomous orbital operations that require the capability of handling imprecise measurements from sensors. Several applications are underway to investigate fuzzy logic approaches and develop guidance and control algorithms for autonomous orbital operations. Translational as well as rotational control of a spacecraft have been demonstrated using space shuttle simulations. An approach to a camera tracking system has been developed to support proximity operations and traffic management around the Space Station Freedom. Pattern recognition and object identification algorithms currently under development will become part of this camera system at an appropriate level in the future. A concept to control environment and life support systems for large Lunar based crew quarters is also under development. Investigations in the area of reinforcement learning, utilizing neural networks, combined with a fuzzy logic controller, are planned as a joint project with the Ames Research Center.

    Full Text Available Path planning and obstacle avoidance are the two major issues in any navigation system. Wavefront propagation algorithm, as a good path planner, can be used to determine an optimal path. Obstacle avoidance can be achieved using possibility theory. Combining these two functions enable a robot to autonomously navigate to its destination. This paper presents the approach and results in implementing an autonomous navigation system for an indoor mobile robot. The system developed is based on a laser sensor used to retrieve data to update a two dimensional world model of therobot environment. Waypoints in the path are incorporated into the obstacle avoidance. Features such as ageing of objects and smooth motion planning are implemented to enhance efficiency and also to cater for dynamic environments.

    The pathogenesis of Raynaud's phenomenon is still unclear. Neural and intravascular mechanisms are thought to be involved in the pathological process. The role of the autonomic nervous system is continually discussed, with particular attention to over-reactivity of the sympathetic part. The aim of this study was the clinical and electrophysiological analysis of autonomic nervous system function in patients with primary Raynaud's phenomenon. Thirty four patients with primary Raynaud's phenomenon and 31 sex and age-matched controls were examined. Neurological examination, modified Low's Questionnaire, orthostatic and sustained handgrip tests, conduction velocity study in three nerves, sympathetic skin response (SSR), and heart rate variability (HRV) during deep breathing and at rest with the fast Fourier transform were performed. In the clinical examinations, 35.3% of the primary Raynaud's patients presented sensory neuropathy, but this was not confirmed in the standard conduction velocity tests. The modified Low's Questionnaire revealed dysautonomy in 82% of the patients. Autonomic regulation during the orthostatic and handgrip tests were within the normal limits. HRV at rest and the E/I ratio were significantly lower in the patient group than in the controls, while HRV spectrum analysis revealed the predominance of the low-frequency band in the patients. These results indicate the presence of sympathetic dysregulation and impairment of parasympathetic modulation of heart function in primary Raynaud's patients. The different cardiovascular and sudomotor functions are not affected to the same degree. These observations might support the theory of a central impairment of autonomic function in primary Raynaud's phenomenon. Peripheral nerve lesion as a coexisting cause of the observed dysautonomy remains uncertain.

    To investigate whether Huntington's disease (HD) affects autonomic nervous system (ANS) functioning. Twenty patients with HD who had positive genetic test results underwent standardised ANS function tests including sympathetic skin responses (SSRs) of the hands and feet, measurements of heart rate variability (HRV), both during five minutes of resting and deep respiration, and an orthostatic blood pressure test. Patients were classified according to the motor subscale of the unified Huntington's disease rating scale (UHDRS; mean (SD) score 26.4 (13.6)) and divided into two subgroups: UHDRS or =25 points (mid stages, M-HD). Autonomic indices were compared with those obtained for a group of well matched healthy controls (n=60). Overall, patients showed lower HRV indices than controls. Multivariate analysis with the independent factor of "group" (controls, E-HD, M-HD) showed a significant group effect on both the high frequency power (F=4.32, p=0.017) and the coefficient of variation (F=4.23, p=0.018), indicating a significant reduction in vagal modulation in the M-HD group. There was a shift in autonomic neurocardiac balance towards sympathetic predominance in the M-HD group compared with controls (F=2.89, p=0.062). Moreover, we found an inverse correlation between the severity of clinical HD symptoms (assessed by the UHDRS) and the modulation of cardiovagal activity (p=0.028). Vagal dysregulation was present in two patients; one of them also showed a pathological blood pressure test and a latency prolongation in the SSRs of the hands. Two other patients had pathologically reduced SSR amplitudes. Only patients of the M-HD group were affected.

    Various planning problems for robotic systems are of considerable interest. One of such problems is the problem of task sequencing. In this paper, we consider the problem of task sequencing for autonomous vacuum floor cleaning robots. We consider a graph model for the problem. We propose an efficient approach to solve the problem. In particular, we use an explicit reduction from the decision version of the problem to the satisfiability problem. We present the results of computational experiments for different satisfiability algorithms.

    Animal swarms displaying a variety of typical flocking patterns would not exist without the underlying safe, optimal and stable dynamics of the individuals. The emergence of these universal patterns can be efficiently reconstructed with agent-based models. If we want to reproduce these patterns with artificial systems, such as autonomous aerial robots, agent-based models can also be used in their control algorithms. However, finding the proper algorithms and thus understanding the essential characteristics of the emergent collective behaviour requires thorough and realistic modeling of the robot and also the environment. In this paper, we first present an abstract mathematical model of an autonomous flying robot. The model takes into account several realistic features, such as time delay and locality of communication, inaccuracy of the on-board sensors and inertial effects. We present two decentralized control algorithms. One is based on a simple self-propelled flocking model of animal collective motion, the other is a collective target tracking algorithm. Both algorithms contain a viscous friction-like term, which aligns the velocities of neighbouring agents parallel to each other. We show that this term can be essential for reducing the inherent instabilities of such a noisy and delayed realistic system. We discuss simulation results on the stability of the control algorithms, and perform real experiments to show the applicability of the algorithms on a group of autonomous quadcopters. In our case, bio-inspiration works in two ways. On the one hand, the whole idea of trying to build and control a swarm of robots comes from the observation that birds tend to flock to optimize their behaviour as a group. On the other hand, by using a realistic simulation framework and studying the group behaviour of autonomous robots we can learn about the major factors influencing the flight of bird flocks.

    2016-12-01

    Full Text Available Recent advances in the research of autonomous vehicles have showed a vast range of applications, such as exploration, surveillance and environmental monitoring. Considering the mining industry, it is possible to use such vehicles in the prospection of minerals of commercial interest beneath the ground. However, tasks such as geophysical surveys are highly dependent on specific sensors, which mostly are not designed to be used in these new range of autonomous vehicles. In this work, we propose a novel magnetic survey pipeline that aims to increase versatility, speed and robustness by using autonomous rotary-wing Unmanned Aerial Vehicles (UAVs. We also discuss the development of a state-of-the-art three-axis fluxgate, where our goal in this work was to refine and adjust the sensor topology and coupled electronics specifically for this type of vehicle and application. The sensor was built with two ring-cores using a specially developed stress-annealed CoFeSiB amorphous ribbon, in order to get sufficient resolution to detect concentrations of small ferrous minerals. Finally, we report on the results of experiments performed with a real UAV in an outdoor environment, showing the efficacy of the methodology in detecting an artificial ferrous anomaly.

  20. Safety performance monitoring of autonomous marine systems

    The marine environment is vast, harsh, and challenging. Unanticipated faults and events might lead to loss of vessels, transported goods, collected scientific data, and business reputation. Hence, systems have to be in place that monitor the safety performance of operation and indicate if it drifts into an intolerable safety level. This article proposes a process for developing safety indicators for the operation of autonomous marine systems (AMS). The condition of safety barriers and resilience engineering form the basis for the development of safety indicators, synthesizing and further adjusting the dual assurance and the resilience based early warning indicator (REWI) approaches. The article locates the process for developing safety indicators in the system life cycle emphasizing a timely implementation of the safety indicators. The resulting safety indicators reflect safety in AMS operation and can assist in planning of operations, in daily operational decision-making, and identification of improvements. Operation of an autonomous underwater vehicle (AUV) exemplifies the process for developing safety indicators and their implementation. The case study shows that the proposed process leads to a comprehensive set of safety indicators. It is expected that application of the resulting safety indicators consequently will contribute to safer operation of current and future AMS. - Highlights: • Process for developing safety indicators for autonomous marine systems. • Safety indicators based on safety barriers and resilience thinking. • Location of the development process in the system lifecycle. • Case study on AUV demonstrating applicability of the process.

In the first place, the specificity of care is explored from a point of view that includes, besides the material aspects, affective and moral ones. It stands out the complexity of care at the different dimensions that operate in this concept. Second: care is changing in our society, starting from the massive and durable arrival of women to the labor market. In the families women are mainly responsible or caring for aged population, children and other fragile people. As to this moment care has not been reorganized among the genders, they have been the women of different generations who have articulated its solidarities with available state help or appealing to the market to cover the necessities of its relatives. Howevwe, the graving deficit in the provision of family care seems to approach a point of not sustainability in the near future. Propoal of “social care” offer institutional articulation between private solidarities and public duties in the allotment of family care so tha society in general can bear to the participation of women in the labour work. This implying the return of moral responsibility in the politics of care.Este artículo propone una reflexión sobre uno de los debates que está generando una importante producción teórica y empírica en los últimos años: los cuidados. Para ello, en primer lugar, se explora la especificidad de los cuidados ampliando el enfoque desde un punto de vista que incluya, además de los aspectos materiales, aspectos afectivos y morales. Se destaca la transversalidad y enorme complejidad de los cuidados por las diferentes dimensiones que operan en dicho concepto.

Una de ellas se forma por los encuentros locales, nacionales e internacionales que sirvieron de plataforma para comunicar, entre mujeres, las propias necesidades para el desarrollo y la liberación de la injusticia, intolerancia y desdén. Las mujeres han luchado por medio de sindicatos y movimientos sociales para plantear justas demandas, entre otras, educación, igual salario por igual trabajo, bienestar, permiso de maternidad, cuidado infantil, autodeterminación, información sexual, igualdad en la participación política y liderazgo. Con el avance teórico en las cuestiones de raza, clase, minorías étnicas y feminismo lésbico, se desarrolló la identidad de la nueva chicana a la luz de la emancipación de las mujeres.

    Ni, Jun; Hu, Jibin

    2017-06-01

    In this paper, a novel dynamics controller for autonomous vehicle to simultaneously control it to the driving limits and follow the desired path is proposed. The dynamics controller consists of longitudinal and lateral controllers. In longitudinal controller, the G-G diagram is utilized to describe the driving and handling limits of the vehicle. The accurate G-G diagram is obtained based on phase plane approach and a nonlinear vehicle dynamic model with accurate tyre model. In lateral controller, the tyre cornering stiffness is estimated to improve the robustness of the controller. The stability analysis of the closed-looped error dynamics shows that the controller remains stable against parameters uncertainties in extreme condition such as tyre saturation. Finally, an electric autonomous Formula race car developed by the authors is used to validate the proposed controller. The autonomous driving experiment on an oval race track shows the efficiency and robustness of the proposed controller.

    La civilización medieval produjo los arquetipos y el impulso dinámico para las fuerzas principales del mundo moderno. Representa el período de gestación de la cultura moderna. La ciencia occidental se desarrolló en las redes de la erudición medieval que en el siglo XII eran las escuelas catedralicias. La catedral de Chartres, simboliza, históricamente los comienzos de nuestra era científica y tecnológica.

    En la escuela de Chartres se establecieron las bases filosóficas para el surgimiento de la ciencia medieval y la moderna. El estudio de la naturaleza se constituyó en disciplina por derecho propio. En Chartres, durante el siglo XII, el estudio de la ciencia obtuvo por primera vez una prioridad definitiva sobre la enseñanza de las artes liberales y los maestros lucharon por la instauración de osadas reformas en la educación superior general centrando el programa de estudios de ciencias naturales en el cuadrivio: aritmética, música (como matemáticas geometría y astronomía y no en las humanidades tradicionales del trivio: gramática, retórica y lógica.

    La escuela de Chartres desafiaba así a los 7 siglos de enseñanzas cristianas a cerca del lugar de la naturaleza en el esquema divino, contra todas las resistencias de las grandes escuelas catedralicias de Orleans, Saint Victor en París y Laon. El ser humano y el mundo eran una unidad en el pensamiento de Chartres; trivio y cuadrivio eran parte de un universo único.

In this paper, we present a longitudinal control algorithm based on cloud model for Mengshi autonomous vehicle to ensure the dynamic stability and tracking performance of Mengshi autonomous vehicle. An experiments is applied to test the implementation of the longitudinal control algorithm. Empirical results show that if the longitudinal control algorithm based Gauss cloud model are applied to calculate the acceleration, and the vehicles drive at different speeds, a stable longitudinal control effect is achieved.

    Amplifying human ability for controlling complex environments featuring autonomous units can be aided by learned models of human and system performance. In developing a command and control system that allows a small number of people to control a large number of autonomous teams, we employ an autonomics framework to manage the networks that represent mission plans and the networks that are composed of human controllers and their autonomous assistants. Machine learning allows us to build models of human and system performance useful for monitoring plans and managing human attention and task loads. Machine learning also aids in the development of tactics that human supervisors can successfully monitor through the command and control system.

    Mobility is a basic necessity of contemporary society and it is a key factor in global economic development. The basic requirements for the transport of people and goods are: safety and duration of travel, but also a number of additional criteria are very important: energy saving, pollution, passenger comfort. Due to advances in hardware and software, automation has penetrated massively in transport systems both on infrastructure and on vehicles, but man is still the key element in vehicle driving. However, the classic concept of ‘human-in-the-loop’ in terms of ‘hands on’ in driving the cars is competing aside from the self-driving startups working towards so-called ‘Level 4 autonomy’, which is defined as “a self-driving system that does not requires human intervention in most scenarios”. In this paper, a conceptual synthesis of the autonomous vehicle issue is made in connection with the artificial intelligence paradigm. It presents a classification of the tasks that take place during the driving of the vehicle and its modeling from the perspective of traditional control engineering and artificial intelligence. The issue of autonomous vehicle management is addressed on three levels: navigation, movement in traffic, respectively effective maneuver and vehicle dynamics control. Each level is then described in terms of specific tasks, such as: route selection, planning and reconfiguration, recognition of traffic signs and reaction to signaling and traffic events, as well as control of effective speed, distance and direction. The approach will lead to a better understanding of the way technology is moving when talking about autonomous cars, smart/intelligent cars or intelligent transport systems. Keywords: self-driving vehicle, artificial intelligence, deep learning, intelligent transport systems.

    Full Text Available The rapid development of high-technology has caused new inventions of gadgets for all walks of life regardless age. In this rapidly advancing technology era many individuals possess hi-tech gadgets such as laptops, tablets, iPad, android phones and smart phones. Adult learners in higher learning institution especially are fond of using smart phones. Students become passive in the classrooms as they are glued to their smart phones. This situation triggers the question of whether learning really takes place while the students are too engaged with their smart phones in the ESL classroom. In this context, the following questions are framed to investigate this issue: What type of learning skills are gained by using smartphones in ESL classrooms? Does smartphone use promote the autonomous learning process? To what extent do learners rely on the lecturers in addition to the usage of smartphones? What are the learning satisfactions gained by ESL learners using smartphones? A total of 70 smartphone users in the age range 18 to 26 years participated in this quantitative study. Questionnaires eliciting demographic details of the respondents, learning skills, learning satisfaction, students' perception on teacher's role in the ESL classroom and autonomous learning were distributed to all the randomly chosen samples. The data were then analyzed by using SPSS version 16. The findings revealed that smartphone use boosted learners’ critical thinking, creative thinking, communication and collaboration skills. In fact, learners gain great satisfaction in the learning process through smartphones. Although learners have moved toward autonomous learning, they are still reliant on the teachers to achieve their learning goals.

    2015-01-01

    As the number of spacecraft in simultaneous operation continues to grow, there is an increased dependency on ground-based navigation support. The current baseline system for deep space navigation utilizes Earth-based radiometric tracking, requiring long-duration observations to perform orbit determination and generate a state update. The age, complexity, and high utilization of the ground assets pose a risk to spacecraft navigation performance. In order to perform complex operations at large distances from Earth, such as extraterrestrial landing and proximity operations, autonomous systems are required. With increasingly complex mission operations, the need for frequent and Earth-independent navigation capabilities is further reinforced. The Multi-spacecraft Autonomous Positioning System (MAPS) takes advantage of the growing interspacecraft communication network and infrastructure to allow for Earth-autonomous state measurements to enable network-based space navigation. A notional concept of operations is given in figure 1. This network is already being implemented and routinely used in Martian communications through the use of the Mars Reconnaissance Orbiter and Mars Odyssey spacecraft as relays for surface assets. The growth of this communications architecture is continued through MAVEN, and future potential commercial Mars telecom orbiters. This growing network provides an initial Marslocal capability for inter-spacecraft communication and navigation. These navigation updates are enabled by cross-communication between assets in the network, coupled with onboard navigation estimation routines to integrate packet travel time to generate ranging measurements. Inter-spacecraft communication allows for frequent state broadcasts and time updates from trusted references. The architecture is a software-based solution, enabling its implementation on a wide variety of current assets, with the operational constraints and measurement accuracy determined by onboard systems.

    Los primeros datos conocidos comenzaron por las observaciones sobre animales y humanos castrados, sobre gigantes y enanos, diabéticos, cotudos y cretinos, y luego sobre las descripciones incipientes de los órganos endocrinos más grandes como el cuerpo tiroides, las cápsulas suprarrenales, testículos, ovarios y la glándula pituitaria. Personajes que podrían perfectamente provenir del país de Lilliput o de un circo del vecindario, tal era su extraña apariencia.

Los grupos armados, milicias o paramilitares, han cumplido funciones reguladoras de las relaciones sociales, implantando "sistemas" autoritarios, restrictivos y el intrusismo. Los órdenes impuestos requieren el sometimiento de los pobladores, tal como algunos lo indican: "Se acostumbran o se adaptan a vivir en aquellos". Debido a tal situación, se pierde buena parte de la autonomía obtenida en el uso de los territorios que han sido construidos, habitados y simbolizados por sus habitantes.

    While many attacks are distributed across botnets, investigators and network operators have recently targeted malicious networks through high profile autonomous system (AS) de-peerings and network shut-downs. In this paper, we explore whether some ASes indeed are safe havens for malicious activity. We look for ISPs and ASes that exhibit disproportionately high malicious behavior using 12 popular blacklists. We find that some ASes have over 80% of their routable IP address space blacklisted and others account for large fractions of blacklisted IPs. Overall, we conclude that examining malicious activity at the AS granularity can unearth networks with lax security or those that harbor cybercrime.

    Full Text Available Menopause is associated with decreased heart rate variability, which is due to reduced parasympathetic or increased sympathetic outflow to the heart. Acute myocardial infarction may be accompanied by decreased heart rate variability. The causes of autonomic dysfunction in postmenopausal women may be multi-factorial i.e., dyslipidemia, increased body fat percentage, aging and loss of female sex hormones. The cardiac vagotonic and sympatholytic effects of estrogen can explain, at least in part, why premenopausal women compared with postmenopausal women have a lower coronary heart disease incidence and mortality rate.

As a result, many tasks have already been identified that unmanned systems could undertake more readily than humans. However, for this to occur, such systems will need to be agile, versatile, persistent, reliable, survivable and lethal. This will require many of the vehicles 'cognitive' or higher order functions to be more fully developed, whereas to date only the 'component' or physical functions have been successfully automated and

    Full Text Available Previous studies have shown that night shift work is thought to be a risk factor for cardiovascular disease and inadequate sleep is a common feature of night shift work. Since it’s more difficult to maintain adequate sleep duration among night watchmen during their working schedule, hence the purpose of our present study was to investigate whether mental stress or fatigue over restricted sleep period in night shift, affects HRV, in order to elucidate on cardiac autonomic modulation among nigh watchmen. With the purpose of this, autonomic activity determined from the levels of the heart rate variability (HRV, and also measured, body mass index (BMI, body fat percentage from skin fold thickness (biceps, triceps, and sub-scapular, supra-iliac among normal sleep watchmen (n = 28 and restricted sleep watchmen (n = 28 at first (1st day, fourth (4th day and seventh (7th day of restricted sleep period. We observed that among restricted sleep individuals, sleepiness was significant increase at 4th day and 7th day when compare to normal sleep individuals, and, there was significant increase in, mean NN, VLF, LF, LF(nu, LF/HF AND significant decrease in SDNN, RMSSD, TSP, HF, and HF(nu at 4th and 7th day of restricted sleep period. In addition to, this variable was more significant increase on 7th day, when compare with 4th day. As well as there was significant negative correlation between LF(nu and HF(nu at subsequent 4th day [r (48 = −0.84; P = 0.01] and 7th day[r (48 = −0.95; P = 0.01] of restricted sleep period. However we didn’t observe any significant variation in BMI, and body fat percentage among restricted sleep individuals when compare to normal sleep individuals with in this restricted sleep periods. Hence we concluded that partial sleep loss may cause autonomic imbalance represented by increased sympathetic and decreased parasympathetic activity; as revealed by altered HRV indices observed in this study.

Other factors like cost, efficiency, and emission penalty of each DG at different loading must be considered since they contribute directly to the total generation cost (TGC...

Provided the rover is given a predefined "ideal rock" definition, the same DEMs can be used to classify rocks in the surrounding area and identify any which meet the ideal rock criteria, meaning that, during long-range traverses potentially scientifically rich rocks would not be missed. The technique can also be used identify the approach trajectory for the arm given the orientation of the rock surface. 1 If several ideal rocks have been identified the rover could then use a rock reachability map to prioritise the rocks for sampling, this would consider: rock classification; the amount of energy required to reach the rock; and the number of instruments that can be placed on the surface. Autonomously identifying ideal rocks and calculating instrument position reduces the rover waiting time and operator input, and increases the scientific return. 1.

    1. Kennedy Space Center (KSC) is developing a mobile launching system with autonomous propellant loading capabilities for liquid-fueled rockets. An autonomous system will be responsible for monitoring and controlling the storage, loading and transferring of cryogenic propellants. The Physics Simulation Software will reproduce the sensor data seen during the delivery of cryogenic fluids including valve positions, pressures, temperatures and flow rates. The simulator will provide insight into the functionality of the propellant systems and demonstrate the effects of potential faults. This will provide verification of the communications protocols and the autonomous system control. 2. The High Pressure Gas Facility (HPGF) stores and distributes hydrogen, nitrogen, helium and high pressure air. The hydrogen and nitrogen are stored in cryogenic liquid state. The cryogenic fluids pose several hazards to operators and the storage and transfer equipment. Constant monitoring of pressures, temperatures and flow rates are required in order to maintain the safety of personnel and equipment during the handling and storage of these commodities.

    Seward, D.; Pace, C.; Morrey, R.; Sommerville, I.

    2000-01-01

    This paper presents an account of carrying out a hazard analysis to define the safety requirements for an autonomous robotic excavator. The work is also relevant to the growing generic class of heavy automated mobile machinery. An overview of the excavator design is provided and the concept of a safety manager is introduced. The safety manager is an autonomous module responsible for all aspects of system operational safety, and is central to the control system's architecture. Each stage of the hazard analysis is described, i.e. system model creation, hazard definition and hazard analysis. Analysis at an early stage of the design process, and on a system that interfaces directly to an unstructured environment, exposes certain issues relevant to the application of current hazard analysis methods. The approach taken in the analysis is described. Finally, it is explained how the results of the hazard analysis have influenced system design, in particular, safety manager specifications. Conclusions are then drawn about the applicability of hazard analysis of requirements in general, and suggestions are made as to how the approach can be taken further

  14. Kinodynamic Motion Planning for Autonomous Vehicles

    2014-06-01

    Full Text Available This article proposes a computationally effective motion planning algorithm for autonomous ground vehicles operating in a semi-structured environment with a mission specified by waypoints, corridor widths and obstacles. The algorithm switches between two kinds of planners, (i static planners and (ii moving obstacle avoidance manoeuvre planners, depending on the mobility of any detected obstacles. While the first is broken down into a path planner and a controller, the second generates a sequence of controls without global path planning. Each subsystem is implemented as follows. The path planner produces an optimal piecewise linear path by applying a variant of cell decomposition and dynamic programming. The piecewise linear path is smoothed by Bézier curves such that the maximum curvatures of the curves are minimized. The controller calculates the highest allowable velocity profile along the path, consistent with the limits on both tangential and radial acceleration and the steering command for the vehicle to track the trajectory using a pure pursuit method. The moving obstacle avoidance manoeuvre produces a sequence of time-optimal local velocities, by minimizing the cost as determined by the safety of the current velocity against obstacles in the velocity obstacle paradigm and the deviation of the current velocity relative to the desired velocity, to satisfy the waypoint constraint. The algorithms are shown to be robust and computationally efficient, and to demonstrate a viable methodology for autonomous vehicle control in the presence of unknown obstacles.

    With advancements of medical technology and improved diagnostic and treatment options, children with severe birth defects who would otherwise have no chance of surviving post birth survive to go home every day. The average lifespan in the United States has increased substantially over the last century. These successes and many other medical breakthroughs in managing complex illnesses, particularly in frail, elderly patients, have resulted in an increasing percentage of patients with comorbidities. This, coupled with a policy change by Medicare (i.e., Medicare will no longer reimburse hospitals for costs associated with treating preventable errors and injuries that a patient acquires while in the hospital), creates an enormous challenge to health care providers. To meet the challenge, the authors propose a new model of health care--the autonomic care system (ACS)--a concept derived from the intensive care unit and the autonomic computing initiative in the computer industry. Using wound care as an example, the authors examine the necessity, feasibility, design, and challenges related to ACS. Specifically, they discuss the role of the human operator, the potential combination of ACS and existing hospital information technology (e.g., electronic medical records and computerized provider order entry), and the costs associated with ACS. ACS may serve as a roadmap to revamp the health care system, bringing down the barriers among different specialties and improving the quality of care for each problem for all hospitalized patients.

    2010-01-01

    Corrosion is a destructive process that often causes failure in metallic components and structures. Protective coatings are the most commonly used method of corrosion control. However, progressively stricter environmental regulations have resulted in the ban of many commercially available corrosion protective coatings due to the harmful effects of their solvents or corrosion inhibitors. This work concerns the development of a multifunctional, smart coating for the autonomous control of corrosion. This coating is being developed to have the inherent ability to detect the chemical changes associated with the onset of corrosion and respond autonomously to control it. The multi-functionality of the coating is based on microencapsulation technology specifically designed for corrosion control applications. This design has, in addition to all the advantages of other existing microcapsules designs, the corrosion controlled release function that allows the delivery of corrosion indicators and inhibitors on demand only when and where they are needed. Corrosion indicators as well as corrosion inhibitors have been incorporated into the microcapsules, blended into several paint systems, and tested for corrosion detection and protection efficacy.

    Full Text Available Nowadays, with highly developed instrumentation, sensing and actuation technologies, it is possible to foresee an important advance in the field of autonomous and/or semi-autonomous transportation systems. Intelligent Transport Systems (ITS have been subjected to very active research for many years, and Bus Rapid Transit (BRT is one area of major interest. Among the most promising transport infrastructures, the articulated bus is an interesting, low cost, high occupancy capacity and friendly option. In this paper, an experimental platform for research on the automatic control of an articulated bus is presented. The aim of the platform is to allow full experimentation in real conditions for testing technological developments and control algorithms. The experimental platform consists of a mobile component (a commercial articulated bus fully instrumented and a ground test area composed of asphalt roads inside the Consejo Superior de Investigaciones Científicas (CSIC premises. This paper focuses also on the development of a human machine interface to ease progress in control system evaluation. Some experimental results are presented in order to show the potential of the proposed platform.

    Full Text Available Autonomous mobile robot field has gain interest among researchers in recent years. The ability of a mobile robot to locate its current position and surrounding environment is the fundamental in order for it to operate autonomously, which commonly known as localization. Localization of mobile robot are commonly affected by the inaccuracy of the sensors. These inaccuracies are caused by various factors which includes internal interferences of the sensor and external environment noises. In order to overcome these noises, a filtering method is required in order to improve the mobile robot’s localization. In this research, a 2- wheeled-drive (2WD mobile robot will be used as platform. The odometers, inertial measurement unit (IMU, and ultrasonic sensors are used for data collection. Data collected is processed using Kalman filter to predict and correct the error from these sensors reading. The differential drive model and measurement model which estimates the environmental noises and predict a correction are used in this research. Based on the simulation and experimental results, the x, y and heading was corrected by converging the error to10 mm, 10 mm and 0.06 rad respectively.

    As robotic ground systems advance in capabilities and begin to fulfill new roles in both civilian and military life, the limitation of slow operational speed has become a hindrance to the wide-spread adoption of these systems. For example, military convoys are reluctant to employ autonomous vehicles when these systems slow their movement from 60 miles per hour down to 40. However, these autonomous systems must operate at these lower speeds due to the limitations of the sensors they employ. Robotic Research, with its extensive experience in ground autonomy and associated problems therein, in conjunction with CERDEC/Night Vision and Electronic Sensors Directorate (NVESD), has performed a study to specify system and detection requirements; determined how current autonomy sensors perform in various scenarios; and analyzed how sensors should be employed to increase operational speeds of ground vehicles. The sensors evaluated in this study include the state of the art in LADAR/LIDAR, Radar, Electro-Optical, and Infrared sensors, and have been analyzed at high speeds to study their effectiveness in detecting and accounting for obstacles and other perception challenges. By creating a common set of testing benchmarks, and by testing in a wide range of real-world conditions, Robotic Research has evaluated where sensors can be successfully employed today; where sensors fall short; and which technologies should be examined and developed further. This study is the first step to achieve the overarching goal of doubling ground vehicle speeds on any given terrain.

    Understanding how autonomous students are capable of regulating their own learning process is essential to develop self-directed teaching methods. To understand how self-directed medical students approach learning in medical schools at University of Concepción, Chile. A qualitative and descriptive study, performed according to Grounded Theory guidelines, following Strauss & Corbin was performed. Twenty medical students were selected by the maximum variation sampling method. The data collection technique was carried out by a semi-structured thematic interview. Students were interviewed by researchers after an informed consent procedure. Data were analyzed by the open coding method using Atlas-ti 7.5.2 software. Self-directed learners were characterized by being good planners and managing their time correctly. Students performed a diligent selection of contents to study based on reliable literature sources, theoretical relevance and type of evaluation. They also emphasized the discussion of clinical cases, where theoretical contents can be applied. This modality allows them to gain a global view of theoretical contents, to verbalize knowledge and to obtain a learning feedback. The learning process of autonomous students is intentional and planned.

    The observation of orthostatic hypotension in an index case of manganese toxicity lead to this prospective attempt to evaluate cardiovascular autonomic function and cognitive and emotional neurotoxicity in eight manganese alloy welders and machinists. The subjects consisted of a convenience sample consisting of an index case of manganese dementia, his four co-workers in a frog shop for gouging, welding, and grinding repair of high manganese railway track and a convenience sample of three mild steel welders with lesser manganese exposure also referred because of cognitive or autonomic symptoms. Frog shop air manganese samples 9.6--10 years before and 1.2--3.4 years after the diagnosis of the index case exceeded 1.0 mg/m{sup 3} in 29% and 0.2 mg/m{sup 3} in 62%. Twenty-four-hour electrocardiographic (Holter) monitoring was used to determine the temporal variability of the heartrate (RR{prime} interval) and the rates of change at low frequency and high frequency. MMPI and MCMI personality assessment and short-term memory, figure copy, controlled oral word association, and symbol digit tests were used.

    Full Text Available Autonomic Computing allows systems like wireless sensor networks (WSN to self-manage computing resources in order to extend their autonomy as much as possible. In addition, contextualization tasks can fuse two or more different sensor data into a more meaningful information. Since these tasks usually run in a single centralized context server (e.g., sink node, the massive volume of data generated by the wireless sensors can lead to a huge information overload in such server. Here we propose DAIM, a distributed autonomic inference machine distributed which allows the sensor nodes to do self-management and contextualization tasks based on fuzzy logic. We have evaluated DAIM in a real sensor network taking into account other inference machines. Experimental results illustrate that DAIM is an energy-efficient contextualization method for WSN, reducing 48.8% of the number of messages sent to the context servers while saving 19.5% of the total amount of energy spent in the network.

    Ensuring reliable communication in next-generation space networks requires a novel network management system to support greater levels of autonomy and greater awareness of the environment and assets. Intelligent Automation, Inc., has developed a security-enhanced autonomous network management (SEANM) approach for space networks through cross-layer negotiation and network monitoring, analysis, and adaptation. The underlying technology is bundle-based delay/disruption-tolerant networking (DTN). The SEANM scheme allows a system to adaptively reconfigure its network elements based on awareness of network conditions, policies, and mission requirements. Although SEANM is generically applicable to any radio network, for validation purposes it has been prototyped and evaluated on two specific networks: a commercial off-the-shelf hardware test-bed using Institute of Electrical Engineers (IEEE) 802.11 Wi-Fi devices and a military hardware test-bed using AN/PRC-154 Rifleman Radio platforms. Testing has demonstrated that SEANM provides autonomous network management resulting in reliable communications in delay/disruptive-prone environments.

    2008-01-01

    Small air vehicles offer challenging power, weight, and volume constraints when considering implementation of system health monitoring technologies. In order to develop a testbed for monitoring the health and integrity of control surface servos and linkages, the Autonomous Aircraft Servo Health Monitoring system has been designed for small Uninhabited Aerial Vehicle (UAV) platforms to detect problematic behavior from servos and the air craft structures they control, This system will serve to verify the structural integrity of an aircraft's servos and linkages and thereby, through early detection of a problematic situation, minimize the chances of an aircraft accident. Embry-Riddle Aeronautical University's rotary-winged UAV has an Airborne Power management unit that is responsible for regulating, distributing, and monitoring the power supplied to the UAV's avionics. The current sensing technology utilized by the Airborne Power Management system is also the basis for the Servo Health system. The Servo Health system measures the current draw of the servos while the servos are in Motion in order to quantify the servo health. During a preflight check, deviations from a known baseline behavior can be logged and their causes found upon closer inspection of the aircraft. The erratic behavior nay include binding as a result of dirt buildup or backlash caused by looseness in the mechanical linkages. Moreover, the Servo Health system will allow elusive problems to be identified and preventative measures taken to avoid unnecessary hazardous conditions in small autonomous aircraft.

    The Microwave Anisotropy Probe (MAP) mission is the second mission in NASA's Office of Space Science low-cost, Medium-class Explorers (MIDEX) program. The Explorers Program is designed to accomplish frequent, low cost, high quality space science investigations utilizing innovative, streamlined, efficient management, design and operations approaches. The MAP spacecraft will produce an accurate full-sky map of the cosmic microwave background temperature fluctuations with high sensitivity and angular resolution. The MAP spacecraft is planned for launch in early 2001, and will be staffed by only single-shift operations. During the rest of the time the spacecraft must be operated autonomously, with personnel available only on an on-call basis. Four (4) innovations will work cooperatively to enable a significant reduction in operations costs for the MAP spacecraft. First, the use of a common ground system for Spacecraft Integration and Test (I&T) as well as Operations. Second, the use of Finite State Modeling for intelligent autonomy. Third, the integration of a graphical planning engine to drive the autonomous systems without an intermediate manual step. And fourth, the ability for distributed operations via Web and pager access.

    2009-01-01

    Fibromyalgia (FM) is a syndrome associated with widespread pain and various other signs and symptoms. Several of these multisystem features could be explained on the basis of autonomic nervous system (ANS) dysfunction. The aim of the present study was to evaluate ANS dysfunction in FM based on time-domain heart rate variability (HRV) analysis and serum neuropeptide Y (NPY) levels in 51 patients with FM, 25 patients with systemic sclerosis (SSc), and 15 healthy controls (NHS). Compared with the SSc and NHS groups, the FM group had significantly higher NPY levels, and in the FM subgroup subjected to HRV analysis (25/51 patients, 49%), certain HRV indices were significantly reduced. In this subgroup, NPY was significantly correlated with the SDANN index and the NN50, but neither NPY or HRV parameters showed any significant correlation with clinical aspects of the FM. These findings suggest that autonomic dysfunction and NPY are crucial elements in the pathophysiology of FM. Additional studies are necessary to define the complex roles played by NPY and ANS in modulating pain and immunological functions of different diseases.

    2013-10-01

    Trigeminal autonomic cephalalgias include cluster headache, paroxysmal hemicrania, and short-lasting unilateral neuralgiform headache attacks with conjunctival injection, tearing, and rhinorrhea (SUNCT). Conventional pharmacological therapy can be successful in the majority of trigeminal autonomic cephalalgias patients. Most cluster headache attacks respond to 100% oxygen inhalation, or 6 mg subcutaneous sumatriptan. Nasal spray of sumatriptan (20 mg) or zolmitriptan (5 mg) are recommended as second choice. The bouts can be brought under control by a short course of corticosteroids (oral prednisone: 60-100 mg/day, or intravenous methylprednisolone: 250-500 mg/day, for 5 days, followed by tapering off the dosage), or by long-term prophylaxis with verapamil (at least 240 mg/day). Alternative long-term preventive medications include lithium carbonate (800-1600 mg/day), methylergonovine (0.4-1.2 mg/day), and topiramate (100-200 mg/day). As a rule, paroxysmal hemicrania responds to preventive treatment with indomethacin (75-150 mg/day). A short course of intravenous lidocaine (1-4 mg/kg/hour) can reduce the flow of attacks during exacerbations of SUNCT. Lamotrigine (100-300 mg/day) is the preventive drug of choice for SUNCT. Gabapentin (800-2700 mg/day), topiramate (50-300 mg/day), and carbamazepine (200-1600 mg/day) may be of help. © 2013 American Headache Society.

    Full Text Available This article examines the questie/ subsidies requested by the Catalan- Aragonese monarchs from the towns of the royal domain of Catalonia between 1309 and 1359. From the point of view of the Crown, the importance of these tributes lies in the fact that they were the monarchy’s main way of financing prior to the transcendental changes in taxation of the decades of 1350 and 1360. And, from the point of view of the towns, the necessity to negotiate with the king and his officials, year after year, the amount of the questie/subsidies due in every small city, contributed to the increasing financial autonomy of the municipalities and, beyond that, to the social and institutional coordination of that community.

Y, desde la perspectiva de las villas, la necesidad de negociar con el rey y sus oficiales, año por año, el volumen de las questie/subsidios a pagar por cada pequeña ciudad contribuyó a la creciente autonomía financiera de los municipios y, más allá, a la vertebración social e institucional de la propia comunidad.

Two focus groups were carried out with family members who are the legal guardians of people with intellectual disability who have received independent living training at the Center for Integral Training and Development (CADI, per its abbreviation in Spansh. Focus group transcripts were analyzed with codes defined a priori, based on an existing theoretical framework on autonomy and quality of life among intellectually disabled persons. Autonomy is exercised by the intellectually disabled in the personal, social, sexual and economic spheres of life. Empowered autonomy implies that the person is taught the necessary skills and then allowed to act upon his or her own interests. Negotiated autonomy includes guidance, explanation and negotiation; it constitutes a learning process. Interpreted autonomy is the most limited type described, and implies protection, interpretation and may involve decision-making by others. These types of autonomy constitute a complex phenomenon and the divisions between them are indistinct.Este estudio busca describir las maneras en que jóvenes y adultos mexicanos con discapacidad intelectual ejercen la autonomía.

    Full Text Available El concepto de autonomía en el que se ha basado tradicionalmente la Bioética proviene de la teoría liberal, y se articula a partir de un sujeto teórico que poco tiene que ver con las personas. Por ello, en este artículo se plantea la necesidad de revisar y reformular el concepto de autonomía para la Bioética. ¿Hay alternativas al modelo liberal de autonomía tan extendido en nuestras sociedades? Se propone la noción de autonomía relacional como término que recoge ese entramado de relaciones y vínculos que posibilitan la libertad y la toma de decisiones propia, y que se adecua de manera más fiel a la realidad social en la que nos encontramos. Por un lado, la autonomía relacional pretende reflejar la red de relaciones que es constitutiva de la persona. Por otro, se desarrolla como concepto que da cuenta de la co-responsabilidad tanto del profesional como del ciudadano a la hora de que sea el paciente quien tome decisiones autónomasAbstract: The autonomy concept on which the Bioethics has been based traditionally comes from the liberal theory, and it articulates from a theoretical subject that little it has to do with the people. For this reason, in this article is exposed the necessity of reviewing and formulating the concept of autonomy for the Bioethics. Are there alternatives to the liberal model of autonomy so extended in our societies? It´s proposed the notion of relational autonomy like a term that gathers that framework of relations and bonds that make possible the freedom and the own decision making, and this is adapted more faithfully to the social reality in which we were. On the one hand, the relational autonomy tries to reflect the network of relations that is constituent of the person. On the other, it is developed like concept that gives account of the Co-responsibility of the professional and the citizen at the time of which the patient who makes independent decisions.

    Full Text Available El artículo analiza la situación actual de las marcas propias en Colombia, teniendo en cuenta su creciente auge al interior de las grandes superficies. Mediante este tipo de marcas el mismo distribuidor vende productos y servicios con su nombre o recurriendo a una marca de su propiedad, compitiendo con las marcas ya posicionadas en el mercado de los fabricantes. El texto se articula, primero, en una contextualización con base en doctrina comparada respecto de las marcas propias. Luego, se aplican las reglas de dichos conceptos doctrinales a la situación actual colombiana. Por último, se plantean dos problemas jurídicos respecto de las marcas propias, uno, analizado desde la propiedad industrial, y el otro, desde las reglas del Estatuto del Consumidor.

    Full Text Available RESUMEN: Los países de América Latina están afectados en diferentes aspectos por el tráfico de drogas. En especial, en los países andinos, esta actividad ha condicionado de manera decisiva el tipo de régimen democrático iniciado en algún caso en la década de 1980, como Perú o Bolivia, o el régimen colombiano. El autor califica a estos regímenes como narcodemocracias por los efectos del tráfico de drogas no sólo en el orden social y económico, que analiza de forma profunda, sino por la politización del narcotráfico. Las respuestas de las democracias han sido bien distintas en los tres casos analizados, afectando, sin embargo, en todos ellos, a la gobernabilidad de las mismas y a su legitimidad.ABSTRACT: Latin American countries are affected by narcotrafico in different aspects. Particularly, in Andean countries, this activity has deeply conditioned the type of democratic regime installed in some cases in the eighties, as Perou and Bolivia, or the colombian regimen. The author characterizes these regimes as narcodemocracias by effects of narcotrafico in them, not only in social and economic arenas, but also by the politization of narcotrafico. Responses of democracies have been very different in these cases analyzed in the article. Nevertheless, in all of them, governability and legitmity of democracy are affected.

    2014-06-01

    The autonomic nervous system functions to control heart rate, blood pressure, respiratory rate, gastrointestinal motility, hormone release, and body temperature on a second-to-second basis. Here we summarize some of the latest literature on autonomic dysfunction, focusing primarily on the perioperative implications. The variety of autonomic dysfunction now extends to a large number of clinical conditions in which the cause or effect of the autonomic component is blurred. Methods for detecting dysautonomia can be as simple as performing a history and physical examination that includes orthostatic vital signs measured in both recumbent and vertical positions; however, specialized laboratories are required for definitive diagnosis. Heart rate variability monitoring is becoming more commonplace in the assessment and understanding of autonomic instability. Degenerative diseases of the autonomic nervous system include Parkinson's disease and multiple system atrophy, with the most serious manifestations being postural hypotension and paradoxical supine hypertension. Other conditions occur in which the autonomic dysfunction is only part of a larger disease process, such as diabetic autonomic neuropathy, traumatic brain injury, and spinal cord injury. Patients with dysautonomia often have unpredictable and paradoxical physiological responses to various perioperative stimuli. Knowledge of the underlying pathophysiology of their condition is required in order to reduce symptom exacerbation and limit morbidity and mortality during the perioperative period.

    The pathogenesis of laryngopharyngeal reflux (LPR) remains unclear. It is linked to but distinct from gastroesophageal reflux disease (GERD), which has been shown to be related to disturbed autonomic regulation. The aim of this study is to investigate whether autonomic dysfunction also plays a role in the pathogenesis of LPR. Case-control study. Tertiary care center. Seventeen patients with LPR and 19 healthy controls, aged between 19 and 50 years, were enrolled in the study. The patients were diagnosed with LPR if they had a reflux symptom index (RSI) ≥ 13 and a reflux finding score (RFS) ≥ 7. Spectral analysis of heart rate variability (HRV) analysis was used to assess autonomic function. Anxiety and depression levels measured by the Beck Anxiety Inventory (BAI) and Beck Depression Inventory II (BDI-II) were also conducted. In HRV analysis, high frequency (HF) represents the parasympathetic activity of the autonomic nervous system, whereas low frequency (LF) represents the total autonomic activity. There were no significant differences in the LF power and HF power between the 2 groups. However, significantly lower HF% (P = .003) and a higher LF/HF ratio (P = .012) were found in patients with LPR, who demonstrated poor autonomic modulation and higher sympathetic activity. Anxiety was also frequently observed in the patient group. The study suggests that autonomic dysfunction seems to be involved in the pathogenesis of LPR. The potential beneficial effect of autonomic nervous system modulation as a therapeutic modality for LPR merits further investigation.

    2017-01-01

    Autonomous Vehicle technology is quickly expanding its market and has found in Silicon Valley, California, a strong foothold for preliminary testing on public roads. In an effort to promote safety and transparency to consumers, the California Department of Motor Vehicles has mandated that reports of accidents involving autonomous vehicles be drafted and made available to the public. The present work shows an in-depth analysis of the accident reports filed by different manufacturers that are testing autonomous vehicles in California (testing data from September 2014 to March 2017). The data provides important information on autonomous vehicles accidents’ dynamics, related to the most frequent types of collisions and impacts, accident frequencies, and other contributing factors. The study also explores important implications related to future testing and validation of semi-autonomous vehicles, tracing the investigation back to current literature as well as to the current regulatory panorama.
